7-Chloro-3-ethyl-9,9-dimethyl-2-tosyl-2,3,3a,4,9,9a-hexahydro-1H-pyrrolo[3,4-b]quinoline.

The asymmetric unit of the title compound, C22H27ClN2O2S, consists of two independent molecules, A and B, with similar conformations. In both molecules, the pyrrolidine rings adopt twist conformations and the tetrahydropyridine rings have half-chair conformations; these rings are trans-fused. In molecule A, the tosyl group is attached equatorially to the pyrrolidine ring, whereas in molecule B it is in a biaxial position. In both molecules, the sulfonyl groups have distorted tetrahedral geometries. Molecules A and B are linked into a two-dimensional network parallel to the ab plane by N—H⋯O and C—H⋯O hydrogen bonds, and C—H⋯π interactions. [ABSTRACT FROM AUTHOR]
