In the title compound, C31H30N2O2S, the pyrrolidine ring adopts a twist conformation while the tetrahydropyridine ring is in a half-chair conformation. The two rings are trans-fused. The pyridine-bound phenyl ring forms dihedral angles of 17.7 (1) and 48.1 (1)°, respectively, with the tosyl and benzyl phenyl rings. The molecular structure is stabilized by an N—H⋯π interaction involving the benzyl phenyl ring. In the molecules translated by one unit along the a axis are linked into chains by C—H⋯π interactions involving the benzene ring of the tosyl group.

InCl3 (20 mol%) was added to a mixture of 2-(N-cinnamyl-N-tosylamino)-3-phenyl propanal (1 mmol) and 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 from a difference map and refined freely. 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 the methyl groups.
Pyrroloquinoline derivatives exhibit antitumor (Ferlin et al., 2005; Dalla Via et al., 2008), cytotoxic (Xiao et al., 2006), antibacterial (Fujita et al., 1996) and interferon-inducing activities (Crenshaw et al., 1976). As part of our studies on pyrroloquinoline derivatives, we report here the
of the title compound.In the title molecule, the pyrrolidine ring adopts a twist conformation; the asymmetry parameter ΔC2[C2—C10] (Duax et al., 1976) and the puckering parameters q2 and φ (Cremer & Pople, 1975) are 7.5 (2)°, 0.394 (2) Å and 96.5 (3)°, respectively. The tosyl group is attached to the pyrrolidine ring in an equatorial position. The tetrahydropyridine ring adopts a half-chair conformation, with Q, θ, φ and ΔC2[C4—C9] values of 0.543 (2) Å, 131.1 (2)°, 93.1 (3)° and 6.6 (2)°, respectively. The phenyl group is attached to the tetrahydropyridine ring in a biaxial position. The C19—C24 phenyl ring forms dihedral angles of 74.0 (1) and 17.7 (1)°, respectively, with the C4—C9 and C12—C17 benzene rings. The C12—C17 and C26—C31 rings are oriented at a dihedral angle of 48.1 (1)°. The molecular structure is stabilized by an N—H···π interaction (Table 1, Fig. 1). Bond lengths and angles are comparable to those observed in the 3-ethyl analogue (Sudha et al., 2008).
In the π interactions (Fig.2, Table 1) involving the benzene ring of the tosyl group.

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 derivatives exhibit antitumor (Ferlin et al., 2005; Dalla Via et al., 2008), cytotoxic (Xiao et al., 2006), antibacterial (Fujita et al., 1996) and interferon-inducing activities (Crenshaw et al., 1976). As part of our studies on pyrroloquinoline derivatives, we report here the crystal structure of the title compound.
In the title molecule, the pyrrolidine ring adopts a twist conformation; the asymmetry parameter ΔC2[C2—C10] (Duax et al., 1976) and the puckering parameters q2 and φ (Cremer & Pople, 1975) are 7.5 (2)°, 0.394 (2) Å and 96.5 (3)°, respectively. The tosyl group is attached to the pyrrolidine ring in an equatorial position. The tetrahydropyridine ring adopts a half-chair conformation, with Q, θ, φ and ΔC2[C4—C9] values of 0.543 (2) Å, 131.1 (2)°, 93.1 (3)° and 6.6 (2)°, respectively. The phenyl group is attached to the tetrahydropyridine ring in a biaxial position. The C19—C24 phenyl ring forms dihedral angles of 74.0 (1) and 17.7 (1)°, respectively, with the C4—C9 and C12—C17 benzene rings. The C12—C17 and C26—C31 rings are oriented at a dihedral angle of 48.1 (1)°. The molecular structure is stabilized by an N—H···π interaction (Table 1, Fig. 1). Bond lengths and angles are comparable to those observed in the 3-ethyl analogue (Sudha et al., 2008).
In the crystal structure, molecules translated by one unit along the a axis are linked into chains by C—H···π interactions (Fig.2, Table 1) involving the benzene ring of the tosyl group.
