In the title compound, C22H28N2O6S2, the 1,4-di­hydro­pyridine (DHP) ring has a flat-boat conformation. The 2-thio­phene ring is disordered over two orientations and is approximately perpendicular to the DHP ring. For each ester group, at the 3- and 5-positions of the DHP ring, the carbonyl group is cis with respect to the conjugated C=C double bond.
