Diethyl 1-(3,4-Dichlorophenyl)-5-oxo-3-(2-thienyl)-2,2-pyrrolidinedicarboxylate

In the title molecule, C₂₀H₁₉Cl₂NO₅S, the pyrrolidine ring is in an envelope conformation. The dichlorophenyl and thiophene rings are planar. Of the two ethoxycarbonyl side chains, one is nearly planar but the other is distorted from planarity. The structure is stabilized by weak C—H...O hydrogen bonds and van der Waals interactions.
