In the title compound, C31H29BrN2O2S, the pyrrolidine ring is in a twist conformation and the tetrahydropyridine ring adopts an with the methine C atom adjacent to the NH group as the flap atom; the two rings are trans-fused. The bromobenzene ring and the nearest phenyl ring form a dihedral angle of 82.72 (10)°. The benzyl phenyl and the tosyl phenyl rings are oriented at a dihedral angle of 75.57 (11)°. An intramolecular N—H⋯π interaction is observed. In the crystal, molecules are linked into chains running along [101] by C—H⋯O hydrogen bonds and the chains are cross-linked via weak C—H⋯π interactions.

InCl3 (20 mol%) was added to a mixture of S-2-(N-cinnamyl-N-tosylamino)-3-phenyl propanal (1 mmol) and p-bromoaniline (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. Colourless blocks of (I) were recrystallized from ethyl acetate solution by slow evaporation.
The N-bound H atom was located in a difference map and refined freely [N—H = 0.83 (3) 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.

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 act as potent inhibitors for PI3-kinase related kinases (Peng et al., 2002) and as HIV integrase inhibitors (Metobo et al., 2009). These derivatives have been investigated as potential anticancer drugs (Ferlin et al., 2005) and are found to exhibit antifungal (Ryu et al., 2009), antibacterial (Tsuji et al., 1995) and antiproliferative (Ferlin et al., 2001) activities. As part of our studies on pyrroloquinoline derivatives, we report here the crystal structure of the title compound.
Bond lengths and angles are comparable with those in chlorine (Chinnakali et al., 2009a) and unbrominated (Chinnakali et al., 2009b) analouges. The pyrrolidine ring adopts a twist conformation, with puckering parameters (Cremer & Pople, 1975) q2 = 0.408 (2) Å and ϕ = 82.2 (3)°. The tetrahydropyridine ring adopts an envelope conformation with C10, the envelope flap, lying 0.713 (2) Å out of the plane formed by the rest of the atoms (N2/C2—C4/C9) of the ring (r.m.s. deviation 0.053 Å). The asymmetry parameter (Duax et al., 1976) ΔCs[C10] = 12.1 (2)° and the puckering parameters (Cremer & Pople, 1975) Q = 0.537 (2) Å, θ = 128.5 (2)° and ϕ = 103.2 (3)°. The dihedral angle between the C4—C9 and C19—C24 rings is 82.72 (10)° and that between the C12—C17 and C26—C31 rings is 75.57 (11)°.
The molecules are linked into chains running along the [101] by C—H···O hydrogen bonds (Fig.2). The chains are cross-linked into a three-dimensional network via C—H···π interactions (Table 2) involving the C4—C9, C12—C17 and C26—C31 rings.
A superposition of the non-H atoms of the chlorine (Chinnakali et al., 2009a) and unbrominated (Chinnakali et al., 2009b) analouges with those of the title molecule using XP in SHELXTL (Sheldrick, 2008) is shown in Fig.3. The title molecule fits well (r.m.s. deviation 0.415 Å) with the unbrominated analouge. But the chlorine and bromine analouges differ significantly in the orientations of the benzyl group. In the title molecule as well as in the unbrominated derivative, the benzyl phenyl rings is oriented in such a way to form an N—H···π interaction. But in the chlorine analouge, the benzyl group is twisted away from the N—H group to form an N—H···Cl hydrogen bond.
