Diethyl 4-methoxyoxalyl-3,5-diphenylpyrrolidine-2,2-dicarboxylate

Abstract

In the title compound, C25H27NO7, the pyrrolidine ring exhibits an envelope conformation and the benzene rings form a dihedral angle of 33.47 (11)°. In the crystal, pairs of N—H...O hydrogen bonds link the molecules into centrosymmetric dimers. Weak C—H...O interactions link the dimers into layers parallel to the bc plane.
