Diethyl 4-(4-acetamidophenyl)-2,6-dimethyl-1,4-dihydropyridine-3,5-dicarboxylate
The title compound, C(21)H(26)N(2)O(5), was unexpectedly obtained as a by-product in the reaction of ethyl acetoacetate, 4-acetamido-benzaldehyde and urea under microwave irradiation. The dihydro-pyridine ring assumes a flattened boat conformation. Inter-molecular N-H⋯O and weak C-H⋯O hydrogen bonding occurs in the crystal.
متن کاملDiethyl 4-(4-ethoxyphenyl)-2,6-dimethyl-1,4-dihydropyridine-3,5-dicarboxylate
In the title compound, C(21)H(27)NO(5), the dihydropyridine ring adopts a boat conformation. The ethoxy-phenyl ring is oriented approximately perpendicular to the planar part of the dihydropyridine ring, making a dihedral angle of 89.45 (6)°. An intra-molecular C-H⋯O hydrogen bond generates an S(6) ring motif. In the crystal structure, neighbouring mol-ecules are linked into chains along the a ...

In the title compound, C(20)H(22)N(2)O(4), the dihedral angle between the roughly planar dihydro-pyridine ring (r.m.s. deviation = 0.092 Å) and the benzene ring is 87.09 (6)°. One of the eth-oxy side chains is disordered over two orientations in a 0.669 (14):0.331 (14) ratio. In the crystal, mol-ecules are linked by N-H⋯N hydrogen bonds, generating chains.
