Methyl 1-methyl-3-p-tolyl-1,2,3,3a,4,11c-hexahydrobenzo[f]chromeno[4,3-b]pyrrole-3a-carboxylate
In the title compound, C(25)H(25)NO(3), the dihydro-pyran ring adopts a half-chair conformation, whereas the pyrrolidine ring is in a twist conformation. The tolyl group is oriented at an angle of 82.92 (7)° with respect to the napthalene ring system. In the crystal structure, mol-ecules are linked into centrosymmetric dimers by C-H⋯π inter-actions involving the benzene ring of the tolyl group.
