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

ABSTRACT: In the title compound, C(27)H(27)NO(4), both the pyrrolidine rings in the pyrrolizine ring system adopt envelope conformations, whereas the dihydro-pyran ring adopts a half-chair conformation. The methoxy-phenyl group is oriented at an angle of 53.72?(4)° with respect to the naphthalene ring system. Intra-molecular C-H?O hydrogen bonds are observed. The crystal structure is stabilized by weak inter-molecular C-H?? inter-actions.
