In the title compound, C17H11Cl6NO4, the configuration of the cycloalkene skeleton is endo,cis. The benzene ring is twisted by 58.94 (8)° from the attached pyrrolidine ring. Two carbonyl groups play a key role in the crystal packing. A short intermolecular C⋯O distance of 3.017 (3) Å reveals that one carbonyl group is involved in dipole–dipole interactions, which link two adjacent enantiomers into an inversion dimer. Another carbonyl group provides an acceptor for the weak intermolecular C—H⋯O hydrogen bonds which link these dimers into layers parallel to (011).

N-(3,5-Dichlorobenzyl)maleimide (2.44 g, 10 mmol) and 5,5-dimethoxy-1,2,3,4-tetrachlorocydopentadiene (2.63 g, 10 mmol) were dissolved in anhydrous toluene (100 ml). Then, the solution was refluxed for 8 h. After the solvent was removed under reduced pressure, the residue was dissolved in ether (150 ml), washed with water and brine, dried over anhydrous sodium sulfate, and concentrated to dryness. The product was purified by flash-chromatography (petroleum ether/ethyl acetate, 6:1) and the title compound was isolated as a white solid (4.16 g, 82%), with melting point between 104 and 106°C.
The crystals appropriate for X-ray data collection were obtained from acetone solution at room temperature after four days.
All H atoms were placed in geometically idealized positions and constrained to ride on their parent atoms with C—H distances of 0.93 Å (0.98 for alicylic CH) for aromatic ring CH, and Uiso(H) = 1.2–1.5 Ueq(C).
The title compound, (I) (Fig. 1), was synthesized from N-(3',5'-dichlorobenzyl)maleimide and 5,5-dimethoxy-1,2,3,4-tetrachlorocydopentadiene. The fused pyrrolidine ring systems are frequently encountered structural units in many synthetically challenging and biologically active
The interest of constructing skeletons of this type was further enlightened by the recent disclosure that the rigid arylcyclo analogues having azatricyclo ring systems show anti-HIV-1, anti-cancer, antiviral, and antibacterial activities (Kossakowski et al., 2006).In (I), the configuration of the cycloalkene skeleton is endo, cis. The dihedral angle of pyrrolidine ring and benzene ring is 58.94 (8)°. Two carbonyl groups play a key role in the crystal packing (Fig. 2). One carbonyl group is involved in dipole-dipole interactions, with C3···O1(-x+2, -y+2, -z) distance of 3.017 (3) Å, which link two adjacent enantiomers into inversion dimers. The other carbonyl group provides an acceptor for two weak intermolecular C—H···O hydrogen bonds (Table 1). These intermoleclular interactions link these dimers into layers parallel to (011).

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. |

The title compound, (I) (Fig. 1), was synthesized from N-(3',5'-dichlorobenzyl)maleimide and 5,5-dimethoxy-1,2,3,4-tetrachlorocydopentadiene. The fused pyrrolidine ring systems are frequently encountered structural units in many synthetically challenging and biologically active alkaloids. The interest of constructing skeletons of this type was further enlightened by the recent disclosure that the rigid arylcyclo analogues having azatricyclo ring systems show anti-HIV-1, anti-cancer, antiviral, and antibacterial activities (Kossakowski et al., 2006).
In (I), the configuration of the cycloalkene skeleton is endo, cis. The dihedral angle of pyrrolidine ring and benzene ring is 58.94 (8)°. Two carbonyl groups play a key role in the crystal packing (Fig. 2). One carbonyl group is involved in dipole-dipole interactions, with C3···O1(-x+2, -y+2, -z) distance of 3.017 (3) Å, which link two adjacent enantiomers into inversion dimers. The other carbonyl group provides an acceptor for two weak intermolecular C—H···O hydrogen bonds (Table 1). These intermoleclular interactions link these dimers into layers parallel to (011).
