Methyl 4-phenyl-1,2,3,3a,4,4a,5,12c-octa-hydronaphtho[1',2':3,2]furo[5,4-b]pyrrolizine-4a-carboxyl-ate.

In the title compound, C(26)H(25)NO(3), both pyrrolidine rings adopt envelope conformations, whereas the dihydro-pyran ring adopts a half-chair conformation. The phenyl ring is oriented at an angle of 27.9 (1)° with respect to the naphthalene ring system. An intra-molecular C-H⋯O hydrogen bond is observed. The crystal packing is stabilized by weak inter-molecular C-H⋯π inter-actions.
