In the title compound (systematic name: methyl 17-cyano-3,6-dimethoxy-4,5 alpha-epoxy-6,14-endo-ethenomorphinan-7-carboxylate), C23H24N2O5, the dihydrofuran ring adopts a twist conformation, while the piperidine ring is in a chair conformation. The benzene-fused cyclohexene ring adopts an envelope conformation. An intramolecular C-H center dot center dot center dot O hydrogen bond is observed. Intermolecular C-H center dot center dot center dot N and C-H center dot center dot center dot O hydrogen bonds form C(5) chains along the a and b axes, respectively, and together they form a three-dimensional network.
