The title molecule, C36H27N3O9, adopts an almost symmetric conformation in which the mean planes of the phthalimido units are inclined at dihedral angles of 81.1 (1), 85.3 (1) and 86.3 (1)° with respect to the plane of the central aromatic ring. The O atoms are involved in intra- and intermolecular C—H⋯O hydrogen bonding. The also features π–π arene interactions [minimum ring centroid separation = 3.683 (2) Å]. The present mode of non-covalent interactions leads to a three-dimensional supramolecular architecture.

A mixture of 1,3,5-tris(bromomethyl)-2,4,6-trimethoxybenzene (5.4 g, 12.0 mmol) and potassium phthalimide (10.0 g, 54.0 mmol) suspended in dry dimethyl sulfoxide (150 ml) was stirred at 120 °C for 8 h. After the mixture was cooled to room temperature, water (300 ml) was added and the formed precipitate was filtered and washed with water (400 ml). Then the precipitate was suspended in water (150 ml), and the suspension was extracted with chloroform (3 x 100 ml). The combined organic layers were washed with brine (100 ml) and water (100 ml), dried over magnesium sulfate and concentrated in vacuo. The desired product was obtained as a white solid after flash
(SiO2, toluene/ethyl acetate 2:1 v/v, Rf = 0.37) in 46% yield (3.5 g, 5.5 mmol).Analysis data: m.p. = 235 °C; 1H-NMR (400 MHz, CDCl3) δ 7.68 (m, 6H), 7.60 (m, 6H), 4.87 (s, 6H), 3.89 (s, 9H) p.p.m.; 13C-NMR (100 MHz, CDCl3) δ 167.83, 159.07, 133.55, 132.03, 122.95, 119.12, 62.21, 32.80 p.p.m..
Suitable crystals of the title compound for X-ray analysis were obtained by slow evaporation of a CHCl3 solution.
Our interest in the title compound, C36H27N3O9, arises from its use as an important precursor in the synthesis of artificial receptors based on trimethoxybenzene-derived core (for a review on acyclic carbohydrate receptors containing a trimethyl- or triethylbenzene scaffold, see: Mazik, 2009). The title compound crystallizes in the
P-1 with one molecule in the asymmetric part of the The interplanar angles between the phthalimido residues are 6.67 (4) (B/C), 48.86 (3) (B/D) and 53.23 (3)° (C/D). According to the three-dimensional arrangement of substituents around the benzene ring the present conformational isomer can be named 1-up, 3,5-down tris(phthalimidomethyl), 2,4-up, 6-down- trimethoxybenzene. The is stabilized by seven C—H···O hydrogen bonds (Desiraju, 2002; Desiraju & Steiner, 1999; Mazik et al., 2001; Steiner, 2002) with phthalimido O atoms O(4), O(7), O(8), O(9) and the ether O atoms O(2), O(3) acting as acceptors [C—H···Ophthal 2.38 - 2.54 Å, C—H···Oether 2.32 - 2.36 Å). This high degree of intramolecular hydrogen bonding may explain the slight twist of the benzene ring with maximum atomic distances from the best plane being -0.044 (1) and 0.027 (1) Å for C(4) and C(3). The packing structure is stabilized by intermolecular C—H···O bonding [C—H···O 2.34 - 2.54 Å, 132.1 - 172.1 °] as well as face-to-face arene interactions (centroid···centroid distances 3.683 (2), 3.693 (2) Å].For hydrogen bonds in the solid state, see: Desiraju (2002); Desiraju & Steiner (1999); Steiner (2002).

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. |

Our interest in the title compound, C36H27N3O9, arises from its use as an important precursor in the synthesis of artificial receptors based on trimethoxybenzene-derived core (for a review on acyclic carbohydrate receptors containing a trimethyl- or triethylbenzene scaffold, see: Mazik, 2009). The title compound crystallizes in the space group P-1 with one molecule in the asymmetric part of the unit cell. The interplanar angles between the phthalimido residues are 6.67 (4) (B/C), 48.86 (3) (B/D) and 53.23 (3)° (C/D). According to the three-dimensional arrangement of substituents around the benzene ring the present conformational isomer can be named 1-up, 3,5-down tris(phthalimidomethyl), 2,4-up, 6-down- trimethoxybenzene. The molecular conformation is stabilized by seven C—H···O hydrogen bonds (Desiraju, 2002; Desiraju & Steiner, 1999; Mazik et al., 2001; Steiner, 2002) with phthalimido O atoms O(4), O(7), O(8), O(9) and the ether O atoms O(2), O(3) acting as acceptors [C—H···Ophthal 2.38 - 2.54 Å, C—H···Oether 2.32 - 2.36 Å). This high degree of intramolecular hydrogen bonding may explain the slight twist of the benzene ring with maximum atomic distances from the best plane being -0.044 (1) and 0.027 (1) Å for C(4) and C(3). The packing structure is stabilized by intermolecular C—H···O bonding [C—H···O 2.34 - 2.54 Å, 132.1 - 172.1 °] as well as face-to-face arene interactions (centroid···centroid distances 3.683 (2), 3.693 (2) Å].
