(Received 6 December 2006; accepted 19 December 2006; online 13 January 2007)

There are no direction-specific inter­actions between the mol­ecules of 3-(2-methoxy­benz­yl)-2-(2-methoxy­phen­yl)-1,3-thia­zolidin-4-one, C18H19NO3S, (I); the mol­ecules of 3-(4-nitro­benz­yl)-2-(4-nitro­phen­yl)-1,3-thia­zolidin-4-one, C16H13N3O5S, (II), are linked by four independent C—H⋯O hydrogen bonds into complex chains of fused rings. In 3-(4-methoxy­benz­yl)-2-(4-methoxy­phen­yl)-1,3-thia­zolidin-4-one, (III), isomeric with (I), the mol­ecules are linked into sheets by a combination of C—H⋯O and C—H⋯π(arene) hydrogen bonds, while in 3-(2-nitro­benz­yl)-2-(2-nitro­phen­yl)-1,3-thia­zolidin-4-one, (IV)[link], isomeric with (II), the sheets are built from three independent C—H⋯O hydrogen bonds and one C—H⋯π(arene) hydrogen bond, and reinforced by an aromatic π–π stacking inter­action. In 3-(2-fluoro­benz­yl)-2-(2-fluoro­phen­yl)-1,3-thia­zolidin-4-one, C16H13F2NOS, (V)[link], where the 2-aryl ring exhibits orientational disorder, the mol­ecules are linked into sheets by a combination of C—H⋯O and C—H⋯π(arene) hydrogen bonds, and the sheets are linked in pairs, forming bilayers, by an aromatic π–π stacking inter­action.

Comment

We report here the mol­ecular and supra­molecular structures of five substituted 2-aryl-3-benzyl-1,3-thia­zolidin-4-ones, (I)–(V)[link], all obtained from the reactions of the corresponding aryl aldehydes with L-valine [(S)-2-amino-3-methyl­propionic acid] and mercaptoacetic acid in the presence of diisopropyl­ethyl­amine (Cunico et al., 2006[Cunico, W., Capri, L. R., Gomes, C. R. B., Sizilio, R. H. & Wardell, S. M. S. V. (2006). Synthesis, pp. 3405-3408.]). The method of synthesis (Cunico et al., 2006[Cunico, W., Capri, L. R., Gomes, C. R. B., Sizilio, R. H. & Wardell, S. M. S. V. (2006). Synthesis, pp. 3405-3408.]) represents a one-stage simplification of a previously published two-stage procedure (Holmes et al., 1995[Holmes, C. P., Chinn, J. P., Look, G. C., Gordon, E. M. & Gallop, M. A. (1995). J. Org. Chem. 60, 7328-7333.]); in this earlier investigation, it was found that, under the forcing reaction conditions required, the use of enantiomerically pure chiral amines consistently led to products with no enantio­selectivity at C2. A preliminary report has appeared on compound (V)[link], establishing proof of the constitution of this unexpected reaction product, but that report gave no stereochemical information nor any discussion of the supra­molecular aggregation (Cunico et al., 2006[Cunico, W., Capri, L. R., Gomes, C. R. B., Sizilio, R. H. & Wardell, S. M. S. V. (2006). Synthesis, pp. 3405-3408.]).

[Scheme 1]

In each of compounds (I)–(V)[link] (Figs. 1[link]–5[link][link][link][link]), atom C2 is a stereogenic centre; all the compounds, as prepared, are racemic despite the use of enantiomerically pure L-valine as the source of the ring N atom. Each compound crystallizes in a centrosymmetric space group and for each the reference mol­ecule was selected as one having the S configuration at C2.

While the amidic portion of the heterocyclic ring is effectively planar in each compound, overall these rings are all non-planar. In each of compounds (I)–(IV)[link], the heterocyclic ring adopts an envelope conformation, folded across the line C2⋯C5, while in compound (V)[link], the ring adopts the half-chair conformation, twisted about the S1—C5 bond. The bond distances and angles present no unusual values. The primary inter­est in the structures is the dramatic influence exerted upon the supra­molecular aggregation by the nature and location of the single substituent in the aryl rings; the structural variation involves both the types of direction-specific inter­molecular inter­action present in the supra­molecular structures and the effects of these inter­actions upon the dimensionality of these structures. We discuss the structures in order of increasing complexity, from the isolated mol­ecules in compound (I)[link] up to the bilayers in compound (V)[link].

There are no direction-specific inter­molecular inter­actions in the crystal structure of compound (I)[link], which thus consists of effectively isolated mol­ecules.

In the structure of compound (II)[link], there are four independent C—H⋯O hydrogen bonds (Table 1[link]), which link the mol­ecules into complex chains. Atoms C2 and C37 in the mol­ecule at (x, y, z) act as hydrogen-bond donors, respectively, to nitro atoms O241 and O342 in the mol­ecules at (x, −1 + y, z) and (x, 1 + y, z), so generating by translation a chain of edge-fused R22(20) rings (Bernstein et al., 1995[Bernstein, J., Davis, R. E., Shimoni, L. & Chang, N.-L. (1995). Angew. Chem. Int. Ed. Engl. 34, 1555-1573.]) running parallel to the [010] direction. This chain is weakly reinforced by a further, rather long and possibly adventitious, inter­action between C32 at (x, y, z) and O342 at (x, 1 + y, z). Pairs of these chains are linked by the final hydrogen bond in which atom C22 in the mol­ecule at (x, y, z) acts as a donor to ring atom O4 in the mol­ecule at (1 − x, 1 − y, 1 − z), so forming a complex chain of rings (Fig. 6[link]). Two such chains, related to one another by the translational symmetry operations, run along the lines ([1\over2], y, 0) and ([1\over2], y, [1\over2]), but there are no direction-specific inter­actions between adjacent chains.

The formation of the hydrogen-bonded sheets in compound (III)[link] is very simple, utilizing only two hydrogen bonds, one of C—H⋯O and one of C—H⋯π(arene) type (Table 2[link]). Atoms C5 and C37 in the mol­ecule at (x, y, z) act as hydrogen-bond donors, respectively, to meth­oxy atom O34 in the mol­ecule at (−1 + x, −1 + y, z) and to the C31–C36 ring in the mol­ecule at (−1 + x, y, z). These inter­actions thus generate by translation a sheet lying parallel to (001) (Fig. 7[link]). Four such sheets pass through each unit cell, in the domains 0.04 < z < 0.31, 0.19 < z < 0.46, 0.54 < z < 0.81 and 0.69 < z < 0.96, but there are no direction-specific inter­molecular inter­actions between the sheets, nor is there any inter­weaving of the pairs of sheets within the domains 0 < z < 0.5 and 0.5 < z < 1.0.

The sheet structure of compound (IV)[link] is much more complex than that in compound (III)[link] and it is most readily analysed in terms of two substructures, built, respectively, from two C—H⋯O hydrogen bonds, and from one C—H⋯O and one C—H⋯π(arene) hydrogen bond (Table 3[link]). In the first of these substructures, atoms C24 and C26 in the mol­ecule at (x, y, z) act as hydrogen-bond donors, respectively, to atoms O4 at (x, 1 + y, z) and O31 at (1 − x, y, [{3\over 2}] − z). Propagation of these two inter­actions by translation and rotation then produces a chain of edge-fused rings running parallel to the [010] direction and generated by the twofold rotation axis along ([1\over2], y, [3\over4]), and containing alternating R22(20) and R44(32) rings (Fig. 8[link]).

In the second substructure, atom C35 in the mol­ecule at (x, y, z) acts as a hydrogen-bond donor to atom O4 in the mol­ecule at (x, −y, −[{1\over 2}] + z), so forming a C(8) chain running parallel to the [001] direction and generated by the c-glide plane at y = 0 (Fig. 9[link]). At the same time, atom C25 at (x, y, z) acts as a donor to the C31–C36 ring in the mol­ecule at (x, 1 − y, [{1\over 2}] + z), so forming another chain along [001], this time generated by the c-glide plane at y = [1\over2]. The combination of these two chains along [001] generates a sheet parallel to (100) (Fig. 9[link]). Hence, the combination of this rather simple two-dimensional substructure with the chain of fused rings (Fig. 8[link]) generates a sheet structure of considerable complexity.

The mol­ecule of compound (V)[link] exhibits disorder in the orientation of the C21–C26 ring, where two orientations are related by a 180° rotation about the C2—C21 bond, so that the F atom is disordered over two sites, denoted F22 and F26 (Fig. 5[link]), with occupancies 0.647 (4) and 0.353 (4), respectively. There are only two hydrogen bonds in the structure of compound (V)[link] (Table 4[link]) and these link the mol­ecules into sheets, pairs of which are further linked into bilayers by a single aromatic π–π stacking inter­action; the formation of the bilayers is not influenced by the disorder. Atom C24 in the mol­ecule at (x, y, z) acts as a hydrogen-bond donor to atom O4 in the mol­ecule at (x, 1 + y, z), so generating by translation a C(9) chain running parallel to the [010] direction. At the same time atom C35 in the mol­ecule at (x, y, z) acts as a donor to the C21–C26 ring in the mol­ecule at (x, [{1\over 2}] − y, −[{1\over 2}] + z), so forming a chain along [001] generated by the c-glide plane at y = 0.25; the combination of the chains along [010] and [001] generates a sheet parallel to (100) (Fig. 10[link]). Two sheets of this type, generated by the c-glide planes at y = [1\over4] and y = [3\over4], and related to one another by inversion, pass through each unit cell and these pairs are linked into bilayers by a centrosymmetric π–π stacking inter­action. The C31–C36 rings in the mol­ecules at (x, y, z) and (1 − x, −y, 1 − z) are strictly parallel with an inter­planar spacing of 3.695 (2) Å; the ring-centroid separation is 3.862 (2) Å, corresponding to a ring-centroid offset of 1.125 (2) Å (Fig. 11[link]).

The supra­molecular structures described here show some marked variations consequent upon changes only in the location or identity of a single substituent common to the two aryl rings. This variation is particularly striking in the pairs of isomeric compounds (I)[link] and (II)[link], containing methyl substituents, and (I)[link] and (IV)[link], containing nitro substituents. Whereas compound (I)[link], containing 2-meth­oxy substituents, adopts a structure exhibiting no direction-specific inter­molecular inter­actions, the isomeric compound (III)[link], containing 4-meth­oxy substituents, aggregates into a two-dimensional structure. On the other hand, compound (IV)[link], containing 2-nitro substituents, has a two-dimensional structure, while the isomeric compound (II)[link], containing 4-nitro substituents, has a supra­molecular structure that is only one-dimensional.

Experimental

Samples of compounds (I)–(V)[link] were prepared according to a published procedure (Cunico et al., 2006[Cunico, W., Capri, L. R., Gomes, C. R. B., Sizilio, R. H. & Wardell, S. M. S. V. (2006).

For compound (I)[link], the space group P21/n was uniquely assigned from the systematic absences; the space group P21/c was similarly assigned for each of compounds (II)[link], (III)[link] and (V)[link]. For compound (IV)[link], the systematic absences permitted Cc and C2/c as possible space groups; C2/c was selected and then confirmed by the structure analysis. All H atoms were located in difference maps and then treated as riding atoms, with C—H distances of 0.95 (aromatic), 0.98 (CH3), 0.99 (CH2) or 1.00 Å (aliphatic CH), and with Uiso(H) = kUeq(C), where k = 1.5 for the methyl groups in (III) and k = 1.2 for all other H atoms. The structure of compound (II)[link] indicated twinning. The TwinRotMAt procedure in PLATON (Spek, 2003[Spek, A. L. (2003). J. Appl. Cryst. 36, 7-13.]) was used to generate a HKLF5 file containing 3641 reflections, with an estimated BASF value of 0.41; the final BASF value was 0.299 (7). Accordingly, the final R factors are high because of the lack of any averaging of equivalent reflections. It was apparent from an early stage that one of the F atoms in compound (V)[link] was disordered over two sites, denoted F22 and F26; the final refined occupancies were 0.647 (4) and 0.353 (4).

Comment top

We report here the molecular and supramolecular structures of five substituted 2-aryl-3-benzyl-1,3-thiazolidin-4-ones, (I)–(V), all obtained from the reactions of the corresponding aryl aldehydes with L-valine [(S)-2-amino-3-methylpropionic acid] and mercaptoacetic acid in the presence of diisopropylethylamine (Cunico et al., 2006). The method of synthesis (Cunico et al., 2006) represents a one-stage simplification of a previously published two-stage procedure (Holmes et al., 1995); in this earlier investigation, it was found that, under the forcing reaction conditions required, the use of enantiomerically pure chiral amines consistently led to products with no enantioselectivity at C2. A preliminary report has appeared on compound (V) establishing proof of constitution of this unexpected reaction product, but that report gave no stereochemical information nor any discussion of the supramolecular aggregation (Cunico et al., 2006).

In each of compounds (I)–(V) (Figs. 1–5), atom C2 is a stereogenic centre; all the compounds, as prepared, are racemic despite the use of enantiomerically pure L-valine as the source of the ring N atom. Each compound crystallizes in a centrosymmetric space group, and for each, the reference molecule was selected as one having the S configuration at C2.

While the amidic portion of the heterocyclic ring is effectively planar in each compound, overall these rings are all non-planar. In each of compounds (I)–(IV), the heterocyclic ring adopts an envelope conformation, folded across the line C2···C5, while in compound (V), the ring adopts the half-chair conformation, twisted about the S1—C5 bond. The bond distances and angles present no unusual values. The primary interest in the structures is the dramatic influence exerted upon the supramolecular aggregation by the nature and location of the single substituent in the aryl rings; the structural variation involves both the types of direction-specific intermolecular interaction present in the supramolecular structures and the effects of these interactions upon the dimensionality of these structures. We discuss the structures in order of increasing complexity, from the isolated molecules in compound (I) up to the bilayers in compound (V).

There are no direction-specific intermolecular interactions in the crystal structure of compound (I), which thus consists of effectively isolated molecules.

In the structure of compound (II), there are four independent C—H···O hydrogen bonds (Table 1) which link the molecules into complex chains. Atoms C2 and C37 in the molecule at (x, y, z) act as hydrogen-bond donors, respectively, to nitro atoms O241 and O342 in the molecules at (x, -1 + y, z) and (x, 1 + y, z), so generating by translation a chain of edge-fused R22(20) rings (Bernstein et al., 1995) running parallel to the [010] direction. This chain is weakly reinforced by a further, rather long and possibly adventitious interaction between C32 at (x, y, z) and O342 at (x, 1 + y, z). Pairs of these chains are linked by the final hydrogen bond in which atom C22 in the molecule at (x, y, z) acts as a donor to ring atom O4 in the molecule at (1 - x, 1 - y, 1 - z), so forming a complex chain of rings (Fig. 6). Two such chains, related to one another by the translational symmetry operations, run along the lines (1/2, y, 0) and (1/2, y, 1/2), but there are no direction-specific interactions between adjacent chains.

The formation of the hydrogen-bonded sheets in compound (III) is very simple, utilizing only two hydrogen bonds, one of C—H.·O and one C—H···π(arene) types (Table 2). Atoms C5 and C37 in the molecule at (x, y, z) act as hydrogen-bond donors, respectively, to methoxy atom O34 in the molecule at (-1 + x, -1 + y, z) and to the C31–C36 ring in the molecule at (-1 + x, y, z). These interactions thus generate by translation a sheet lying parallel to (001) (Fig. 7). Four such sheets pass through each unit cell, in the domains 0.04 < z < 0.31, 0.19 < z < 0.46, 0.54 < z < 0.81, 0.69 < z < 0.96, but there are no direction-specific intermolecular interactions between the sheets, nor is there any interweaving of the pairs of sheets within the domains 0 < z < 0.5 and 0.5 < z < 1.0.

The sheet structure of compound (IV) is much more complex than that in compound (III) and it is most readily analysed in terms of two substructures, built, respectively, from two C—H···O hydrogen bonds, and from one C—H.·O and one C—H···π(arene) hydrogen bond (Table 3). In the first of these substructures, atoms C24 and C26 in the molecule at (x, y, z) act as hydrogen-bond donors, respectively, to atoms O4 at (x, 1 + y, z) and O31 at (1 - x, y, 3/2 - z). Propagation of these two interactions by translation and rotation then produces a chain of edge-fused rings running parallel to the [010] direction and generated by the twofold rotation axis along (1/2, y, 3/4), and containing alternating R22(20) and R44(32) rings (Fig. 8).

In the second substructure, atom C35 in the molecule at (x, y, z) acts as a hydrogen-bond donor to atom O4 in the molecule at (x, -y, -1/2 + z), so forming a C(8) chain running parallel to the [001] direction and generated by the c-glide plane at y = 0 (Fig. 9). At the same time, atom C25 at (x, y, z) acts as a donor to the C31–C36 ring in the molecule at (x, 1 - y, 1/2 + z), so forming another chain along [001], this time generated by the c-glide plane at y = 1/2. The combination of these two chains along [001] generates a sheet parallel to (100) (Fig. 9). Hence the combination of this rather simple two-dimensional substructure with the chain of fused rings (Fig. 8) generates a sheet structure of considerable complexity.

The molecule of compound (V) exhibits disorder in the orientation of the C21—C26 ring, where two orientations are related by a 180° rotation about the C2—C21 bond, so that the F atom is disordered over two sites, denoted F22 and F26 (Fig. 5), with occupancies 0.647 (4) and 0.353 (4), respectively. There are only two hydrogen bonds in the structure of compound (V) (Table 4), and these link the molecules into sheets, pairs of which are further linked into bilayers by a single aromatic π–π stacking interaction; the formation of the bilayers is not influenced by the disorder. Atom C24 in the molecule at (x, y, z) acts as a hydrogen-bond donor to atom O4 in the molecule at (x, 1 + y, z), so generating by translation a C(9) chain running parallel to the [010] direction. At the same time atom C35 in the molecule at (x, y, z) acts as a donor to the C21–C26 ring in the molecule at (x, 1/2 - y, -1/2 + z), so forming a chain along [001] generated by the c-glide plane at y = 0.25: the combination of the chains along [010] and [001] generates a sheet parallel to (100) (Fig. 10). Two sheets of this type, generated by the c-glide planes at y = 1/4 and y = 3/4, and related to one another by inversion, pass through each unit cell and these pairs are linked into bilayers by a centrosymmetric π–π stacking interaction. The C31–C36 rings in the molecules at (x, y, z) and (1 - x, -y, 1 - z) are strictly parallel with an interplanar spacing of 3.695 (2) Å; the ring-centroid separation is 3.862 (2) Å, corresponding to a ring-centroid offset of 1.125 (2) Å (Fig. 11).

The supramolecular structures described here show some marked variations consequent upon changes only in the location or identity of a single substituent common to the two aryl rings. This variation is particularly striking in the pairs of isomeric compounds (I) and (II), containing methyl substituents, and (I) and (IV) containing nitro substituents. Whereas compound (I), containing 2-methoxy substituents, adopts a structure exhibiting no direction-specific intermolecular interactions, the isomeric compound (III), containing 4-methoxy substituents, aggregates into a two-dimensional structure. On the other hand, compound (IV), containing 2-nitro substituents, has a two-dimensional structure, while the isomeric compound (II), containing 4-nitro substituents, has a supramolecular structure that is only one-dimensional.

Samples of compounds (I)–(V) were prepared according to the published procedure (Cunico et al., 2006); crystals suitable for single-crystal X-ray diffraction were grown by slow evaporation of solutions in ethanol.

Refinement top

For compound (I), the space group P21/n was uniquely assigned from the systematic absences; the space group P21/c was similarly assigned for each of compounds (II), (III) and (V). For compound (IV), the systematic absences permitted Cc and C2/c as possible space groups; C2/c was selected and then confirmed by the structure analysis. All H atoms were located in difference maps and then treated as riding atoms, with C—H distances of 0.95 Å (aromatic), 0.98 Å (CH3), 0.99 Å (CH2) or 1.00 (aliphatic CH), and with Uiso(H) = kUeq(C), where k = 1.5 for the methyl groups in (III) and 1.2 for all other H atoms. The structure of compound (II) indicated twinning. The TwinRotMAt procedure in PLATON (Spek, 2003) was used to generate an HKLF5 file containing 3641 reflections, with an estimated BASF value of 0.41; the final BASF value was 0.299 (7). Accordingly the final R factors are high, because of the lack of any averaging of equivalent reflections. It was apparent from an early stage that one of the F atoms in compound (V) was disordered over two sites, denoted F22 and F26; the final refined occupancies were 0.647 (4) and 0.353 (4).
