In the title compound, C32H32N2O3S, the pyrrolidine ring adopts an with the methine C atom nearest to the phenyl ring as the flap atom. The tetrahydropyridine ring has a half-chair conformation. The two rings are trans-fused. The phenyl ring bound to the tetrahydropyridine is oriented almost perpendicular [dihedral angle = 86.35 (10)°] to the fused benzene ring. The dihedral angle between the benzylphenyl ring and the sulfonyl-bound phenyl ring is 69.43 (10)°. A very weak N—H⋯π interaction is observed in the molecular structure. In the crystal, molecules translated one unit along the b axis are linked into C(10) chains by C—H⋯O hydrogen bonds; adjacent chains are linked via C—H⋯π interactions, forming a two-dimensional network parallel to the bc plane.

InCl3 (20 mol%) was added to a mixture of 2-(N-cinnamyl-N-tosylamino)-3-phenyl propanal (1 mmol) and p-methoxy aniline (1 mmol) in acetonitrile (20 ml). The reaction mixture was stirred at room temperature for 1 min. On completion of the reaction, as indicated by TLC, the mixture was quenched with water and extracted with ethyl acetate. The organic layer was washed with brine and dried over Na2SO4. The solvent was evaporated in vacuo and the crude product was chromatographed on silica gel using a hexane-ethyl acetate (8.5:1.5 v/v) mixture to obtain the title compound. The compound was recrystallized from ethyl acetate solution by slow evaporation.
The N-bound H atom was located in a difference map and refined freely [N—H = 0.88 (2) Å]. The remaining H atoms were positioned geometrically (C—H = 0.93–0.98 Å) and allowed to ride on their parent atoms, with Uiso(H) = 1.2Ueq(C) or 1.5Ueq(Cmethyl). A rotating group model was used for methyl groups. Reflection 100 was partially obscured by the beam stop and was omitted.
Pyrroloquinoline compounds exhibit antifungal (Ryu et al., 2009), antibacterial (Tsuji et al., 1995) and antiproliferative (Ferlin et al., 2001) activities. We report here the
of the title compound, a pyrrolo[3,4-b]quinoline derivative.The pyrrolidine ring adopts an φ = 78.2 (3)°. The tosyl group is attached to the pyrrolidine ring in a biaxial position. The tetrahydropyridine ring adopts a half-chair conformation with an asymmetry parameter ΔC2[C2—C10] of 7.6 (2)°. The phenyl group attached to the tetrahydropyridine ring is also in a biaxial position. The dihedral angle between the C4—C9 and C19—C24 rings is 86.35 (10)° and that between the C12—C17 and C26—C31 rings is 69.43 (10)°. A very weak N—H···π interaction (Table 1) is observed in the molecular structure. Bond lengths and angles are comparable with those observed in related structures (Sudha et al., 2007,2008a,b).

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. |

Pyrroloquinoline compounds exhibit antifungal (Ryu et al., 2009), antibacterial (Tsuji et al., 1995) and antiproliferative (Ferlin et al., 2001) activities. We report here the crystal structure of the title compound, a pyrrolo[3,4-b]quinoline derivative.
The pyrrolidine ring adopts an envelope conformation with C2 as the flap atom. Atom C2 deviates by 0.663 (3) Å from the plane passing through the other four atoms of the ring (r.m.s. deviation 0.020 Å). The asymmetry parameter (Duax et al., 1976) ΔCs[C2] = 5.4 (2)° and the puckering parameters (Cremer & Pople, 1975) q2 = 0.439 (2) Å and φ = 78.2 (3)°. The tosyl group is attached to the pyrrolidine ring in a biaxial position. The tetrahydropyridine ring adopts a half-chair conformation with an asymmetry parameter ΔC2[C2—C10] of 7.6 (2)°. The phenyl group attached to the tetrahydropyridine ring is also in a biaxial position. The dihedral angle between the C4—C9 and C19—C24 rings is 86.35 (10)° and that between the C12—C17 and C26—C31 rings is 69.43 (10)°. A very weak N—H···π interaction (Table 1) is observed in the molecular structure. Bond lengths and angles are comparable with those observed in related structures (Sudha et al., 2007,2008a,b).
In the crystal structure, molecules translated one unit along the b axis are linked into C(10) chains by C—H···O hydrogen bonds. Glide-related molecules in adjacent chains are linked via C—H···π interactions involving the C4—C9 ring, forming a two-dimensional network parallel to the bc plane (Fig. 2).
