Crystal Structure of Methyl 3-(4-chlorophenyl)-1,2,3,3a,4,9b-hexahydro-1-chromeno[4,3-b]pyrrole-3a-carboxylate

Abstract

The title compound (C₂₀H₂₀NO₃Cl) crystallizes in the triclinic space group P1 with a molecule in the asymmetric unit. The structure was solved by direct methods and refined by full-matrix least-squares procedures to a final R = 0.0397 and wR = 0.1026 using 3171 reflections. The pyrrolidine and the heterocyclic six-membered rings adopt half chair and twist conformations, respectively. The molecules are stabilized by C-H…O type intra and intermolecular interactions in addition to van der Walls forces.
