2,2-Diethyl 3,4-dimethyl 5-(4-cyano-phen-yl)pyrrolidine-2,2,3,4-tetra-carboxyl-ate.


ABSTRACT: The title compound, C(21)H(24)N(2)O(8), was synthesized by a 1,3-dipolar cyclo-addition reaction of dimethyl fumarate, diethyl 2-amino-malonate and 4-cyano-benzaldehyde. Both methyl ester groups display a trans configuration and the pyrrolidine ring possesses an envelope conformation, with the C atom in the 3-position as the flap. In the crystal, N-H?N hydrogen bonds and weak C-H?O inter-actions occur.
