3-Benzyl-7-methoxy-9-phenyl-2-tosyl-2,3,3a,4,9,9a-hexahydro-1H-pyrrolo[3,4-b]quinoline

In the title compound, C32H32N2O3S, the pyrrolidine ring adopts an envelope conformation with the methine C atom nearest to the phenyl ring as the flap atom. The tetrahydro-pyridine 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)degrees] to the fused benzene ring. The dihedral angle between the benzylphenyl ring and the sulfonyl-bound phenyl ring is 69.43 (10)degrees. A very weak N-H center dot center dot center dot pi 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 center dot center dot center dot O hydrogen bonds; adjacent chains are linked via C-H center dot center dot center dot pi interactions, forming a two-dimensional network parallel to the bc plane.
