چکیده

In the title compound, C(28)H(32)N(2)O(7), the 1,4-dihydro-pyridine ring adopts a flattened boat conformation. The two benzene rings are approximately perpendicular to the dihydro-pyridine ring, forming dihedral angles of 84.29 (9) and 82.96 (9)° with the mean plane of the 1,4-dihydro-pyridine unit, whereas the ester groups are only slightly twisted relative to this plane, with dihedral angles of 10.6 (1) and 9.0 (1)°.
