Abstract:
In the title compound, C34H25ClN2O2, the fused pyrrolidine ring adopts an envelope conformation with the N atom as the flap. The two adjacent cyclo-pentane rings also adopt envelope conformations. The mean plane of the pyrrolidine ring makes dihedral angles of 40.53 (10) and 80.23 (10)° with the mean planes of the cyclo-pentane rings. The dihedral angle between the mean planes of the cyclo-pentane rings is 46.71 (9)°. An intra-molecular O-H⋯N hydrogen bond is observed. In the crystal, mol-ecules are linked by C-H⋯O, C-H⋯N and C-H⋯π inter-actions, forming a layer parallel to (10-2).
