1-Methyl-3-(2-methyl-phen-yl)-3a-nitro-1,2,3,3a,4,9b-hexa-hydro-chromeno[4,3-b]pyrrole.
The asymmetric unit of the title compound, C(19)H(20)N(2)O(3), contains two independent mol-ecules in both of which the pyrrolidine ring adopts an envelope conformation, but with a C atom as the flap in one mol-ecule and the N atom in the other. The pyran ring adopts a half-chair conformation in both mol-ecules. In the crystal, mol-ecules are linked via C-H⋯O hydrogen bonds and C-H⋯π inter-actions.
