2,2-Diethyl 3,4-dimethyl 5-(4-cyanophenyl)pyrrolidine-2,2,3,4-tetracarboxylate

2,2-Diethyl 3,4-dimethyl 5-(4-cyanophenyl)pyrrolidine-2,2,3,4-tetracarboxylate

The title compound, C21H24N2O8, was synthesized by a 1,3-dipolar cycloaddition reaction of dimethyl fumarate, diethyl 2-aminomalonate and 4-cyanobenzaldehyde. Both methyl ester groups display a trans configuration and the pyrrolidine ring possesses an envelope conformation, with the C atom in the 3-...
