Methyl 4-(4-chlorophenyl)-1,2,3,3a,4,4a,5,12c-octahydrobenzo[f]chromeno[3,4-b]pyrrolizine-4a-carboxylate

Abstract

There are two molecules in the asymmetric unit of the title compound, C26H24ClNO3. The dihedral angles between the naphthalene ring system and the chlorophenyl substituent are 58.76 (9) and 51.59 (8)° in the two molecules. In the pyrrolizine ring system, both the pyrrolidine rings adopt envelope conformations and the dihydropyran rings adopt half-chair conformations. In the pyrrolizine ring system of one of the molecules, 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 intramolecular C—H...O interactions and the crystal packing is stabilized by weak C—H...π interactions.
