(Received 2 September 2011; accepted 4 September 2011; online 14 September 2011)

The title compound, C24H26N2O8, was synthesized by the cyclo­addition reaction of methyl 2-phenyl­acrylate, diethyl 2-amino­malonate and 4-nitro­benzaldehyde. The pyrrolidine ring exhibits an envelope conformation. The two benzene rings are located on opposite sides of the pyrrolidine ring and subtend a dihedral angle of 59.16 (14)°. The crystal packing is stabilized by N—H⋯O and weak C—H⋯O hydrogen bonding.

Comment top

Substituted pyrrolidine compound is an important class of heterocyclic compounds with wide spread applications to the synthesis of biologically active compounds and natural products (Coldham & Hufton, 2005; Nair & Suja, 2007; Pandey et al., 2006; Sardina & Rapoport, 1996). Its crystal structure is reported here.

The molecular structure of (I) is shown in (Table 2). Bond lengths and angles in (I) are normal. The pyrrolidine ring possesses an envelope conformation. The dihedral angle between the C1—C6 and C13—C18 benzene planes is 59.16 (14)°. The crystal packing is stabilized by N—H···O and C—H···O hydrogen bonds (Table 1).

Experimental top

Diethyl 2-aminomalonate (0.0175 g, 0.1 mmol) were added to a solution of 4-nitrobenzaldehyde (0.018 g, 0.12 mmol) and methyl 2-phenylacrylate (0.08 g, 0.5 mmol) in dichloromethane (1 ml). To the stirred mixture, acetic acid (0.003 g, 0.05 mmol) was added. After the mixture had been stirred at 298 K for 24 h, the reaction was quenched with a saturated solution of sodium bicarbonate (5 ml). The mixture was extracted with diethyl ether, evaporated and separated by flash chromatograghy. A colourless powder was obtained. Single crystals suitable for X-ray diffraction were obtained by slow evaporation of an ethanol solution.

Refinement top

Imino H atom was placed in chemical sensible position and refined isotropically. The remaining carbon-bound H atoms were placed in calculated positions, with C—H = 0.93–0.99 Å, and refined using a riding model, with Uiso(H) = 1.5Ueq(C) for methyl H atoms and 1.2Ueq(C) for the others.

Special details top

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.
