To a solution of 1,3-dimethyl-pyrimidine-2,4,6-trione (1 mmol) in dry toluene (20 ml), the corresponding 2-(N-cinnamyl-N-tosylamino)acetaldehyde (1 mmol) and catalytic amount of the base ethylenediamine-N,N'-diacetate (EDDA) were added and the reaction mixture was refluxed for 12 h. After completion of reaction, the solvent was evaporated under reduced pressure and the crude product was chromatographed using a hexane-ethyl acetate (8:2 v/v) mixture to obtain the title compound. The compound was recrystallized from ethyl acetate solution by slow evaporation.
H atoms were positioned geometrically and constrained to ride on their parent atoms [for methyl H atoms, C—H = 0.96 Å and Uiso(H) = 1.5Ueq(C), for aromatic C—H = 0.93 Å and methine C—H = 0.98 Å, and Uiso(H) = 1.2Ueq(C)]. A rotating group model was used for the methyl groups attached to aromatic rings.
Pyranopyrimidine derivatives exhibit antiviral (Shamroukh et al., 2007) and antimicrobial activities (Bedair et al., 2000, 2001; Eid et al., 2004; Abdel Fattah et al., 2004). We report here the crystal structure of the title compound, a pyranopyrimidine derivative.
In the title molecule, all geometric parameters show normal values (Allen et al., 1987). The significant widening of the O1—S1—O2 [120.49 (6)°] angle from the ideal tetrahedral value is the result of the non-bonding interactions between the short S═O bonds. The sum of the angles around the pyrrolidine N atom (348.3 °) indicates sp3-hybridization.
The pyrrolidine ring has an envelope conformation, with C1, the envelope flap, lying 0.573 (2) Å from the plane defined by C2, C3, C4 and N1 atoms. The Cremer and Pople puckering parameters (Cremer & Pople, 1975) are q = 0.374 (1) Å and φ = 219.9 (2)°; the asymmetry parameter (Duax et al., 1976) ΔCs[C1] is 1.6 (1)°. The tosyl group is equatorially attached to the pyrrolidine ring.
The dihydropyran ring (O3/C5/C2/C3/C7/C6) also adopts an enveope conformation, with atom C5 deviating from the O3/C2/C3/C7/C6 plane by 0.655 (2) Å; the lowest asymmetry parameter is ΔCs[C5] = 7.7 (1)°, and the puckering parameters Q, θ and φ are 0.480 (1) Å, 123.4 (1)° and 252.4 (2)°, respectively. The phenyl ring is equatorially attached to the dihydropyran ring.
The C2—C4/N1 plane forms dihedral angles of 55.26 (5) and 84.93 (4)°, respectively, with the O3/C2/C3/C7/C6 and C8—C13 planes. The O3/C2/C3/C7/C6 plane forms dihedral angles of 7.04 (6) and 74.98 (4)°, respectively, with the pyrimidine (C7/C6/N2/C15/N3/C16) and pheny (C17—C22) planes. Atoms O4, O5, C23 and C24 deviate from the pyrimidine ring plane by 0.101 (2), 0.009 (2), 0.149 (2) and -0.072 (2) Å, respectively.
The glide-related molecules are linked to form a C(6) chain along the c axis by C10—H10···O1i hydrogen bonds. The molecules of the adjacent chains are cross-linked via C18—H18···O4ii and C20—H20···Cg1iii (Cg1 is the C8—C13 ring centroid) interactions, forming a two-dimensional network parallel to the bc plane (Fig. 2). In the network, pairs of C18—H18···O4 hydrogen bonds generate R22(18) ring motif.

Experimental. The low-temparture data was collected with the Oxford Cyrosystem Cobra low-temperature attachment. |
Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

Pyranopyrimidine derivatives exhibit antiviral (Shamroukh et al., 2007) and antimicrobial activities (Bedair et al., 2000, 2001; Eid et al., 2004; Abdel Fattah et al., 2004). We report here the crystal structure of the title compound, a pyranopyrimidine derivative.
In the title molecule, all geometric parameters show normal values (Allen et al., 1987). The significant widening of the O1—S1—O2 [120.49 (6)°] angle from the ideal tetrahedral value is the result of the non-bonding interactions between the short S═O bonds. The sum of the angles around the pyrrolidine N atom (348.3 °) indicates sp3-hybridization.
The pyrrolidine ring has an envelope conformation, with C1, the envelope flap, lying 0.573 (2) Å from the plane defined by C2, C3, C4 and N1 atoms. The Cremer and Pople puckering parameters (Cremer & Pople, 1975) are q = 0.374 (1) Å and φ = 219.9 (2)°; the asymmetry parameter (Duax et al., 1976) ΔCs[C1] is 1.6 (1)°. The tosyl group is equatorially attached to the pyrrolidine ring.
The dihydropyran ring (O3/C5/C2/C3/C7/C6) also adopts an enveope conformation, with atom C5 deviating from the O3/C2/C3/C7/C6 plane by 0.655 (2) Å; the lowest asymmetry parameter is ΔCs[C5] = 7.7 (1)°, and the puckering parameters Q, θ and φ are 0.480 (1) Å, 123.4 (1)° and 252.4 (2)°, respectively. The phenyl ring is equatorially attached to the dihydropyran ring.
The C2—C4/N1 plane forms dihedral angles of 55.26 (5) and 84.93 (4)°, respectively, with the O3/C2/C3/C7/C6 and C8—C13 planes. The O3/C2/C3/C7/C6 plane forms dihedral angles of 7.04 (6) and 74.98 (4)°, respectively, with the pyrimidine (C7/C6/N2/C15/N3/C16) and pheny (C17—C22) planes. Atoms O4, O5, C23 and C24 deviate from the pyrimidine ring plane by 0.101 (2), 0.009 (2), 0.149 (2) and -0.072 (2) Å, respectively.
The glide-related molecules are linked to form a C(6) chain along the c axis by C10—H10···O1i hydrogen bonds. The molecules of the adjacent chains are cross-linked via C18—H18···O4ii and C20—H20···Cg1iii (Cg1 is the C8—C13 ring centroid) interactions, forming a two-dimensional network parallel to the bc plane (Fig. 2). In the network, pairs of C18—H18···O4 hydrogen bonds generate R22(18) ring motif.
