Abstract
In the title compound, C35H30N2O5Se, the pyrrolidine ring adopts an envelope conformation and the oxazolidine ring is in a twist conformation. The tetrahydropyran ring adopts a half-chair conformation. The methoxyphenyl ring is twisted away from the attached azetidinone ring by 15.7 (1)degrees. In the crystal structure, intermolecular C-H center dot center dot center dot O interactions link the molecules into a two-dimensional network.
