Methyl 4-(4-chloro-phen-yl)-1,2,3,3a,4,4a,5,12c-octa-hydro-benzo[f]chromeno[3,4-b]pyrrolizine-4a-carboxyl-ate.

ABSTRACT: There are two mol-ecules in the asymmetric unit of the title compound, C(26)H(24)ClNO(3). The dihedral angles between the naphthalene ring system and the chloro-phenyl substituent are 58.76?(9) and 51.59?(8)° in the two mol-ecules. In the pyrrolizine ring system, both the pyrrolidine rings adopt envelope conformations and the dihydro-pyran rings adopt half-chair conformations. In the pyrrolizine ring system of one of the mol-ecules, one of the C atoms is disordered over two positions with site occupancies of 0.69?(2) and 0.31?(2). The crystal packing is stabilized by weak intra-molecular C-H?O inter-actions and the crystal packing is stabilized by weak C-H?? inter-actions.
