The title compound, C 27 H 28 N 2 O 7 , has been synthesized by the reaction of 2-methoxyethyl 2-(3-nitrobenzylidene)acetoacetate with cinnamyl 3-aminocrotonate and crystallized from methanol. The substituted 1,4-dihydropyridine ring adopts a flattened boat conformation. The 3-nitrophenyl ring is ap
In the title compound, C 19 H 20 N 2 O 7 , the C atom in the 4position of the dihydropyridine ring is displaced out of the plane by 0.0461 (2) A ˚. The dihydropyridine ring plane is almost perpendicular to the benzene ring, with a dihedral angle of 88.9 (3) .
