Diethyl 2,6-dimethyl-4-p-tolyl-1,4-dihydro-pyridine-3,5-dicarboxyl-ate.

ABSTRACT: In the title compound, C(20)H(25)NO(4), the 1,4-dihydro-pyridine ring adopts a flattened-boat conformation and forms a dihedral angle of 89.77?(8)° with the benzene ring. Inter-molecular N-H?O hydrogen bonds result in the formation of extended chains parallel to the b axis.

Diethyl 2,6-dimethyl-4-phenyl-1,4-dihydro-pyridine-3,5-dicarboxyl-ate.

Project description:The title mol-ecule, C(19)H(23)NO(4), was synthesized by the reaction of benzaldehyde, ethyl acetoacetate and NH(4)HCO(3). The dihydro-pyridine ring adopts a flattened boat conformation and the plane of the base of the boat forms a dihedral angle of 88.78 (9)° with the phenyl ring. The packing is stabilized by strong inter-molecular N-H⋯O and weak inter-molecular C-H⋯O hydrogen bonds.

Dimethyl 2,6-dimethyl-1,4-dihydro-pyridine-3,5-dicarboxyl-ate.

Project description:In the crystal of the title compound, C(11)H(15)NO(4), the mol-ecules are linked into sheets by N-H?O and C-H?O hydrogen bonds. Within the mol-ecule, the 1,4-dihydro-pyridine ring exhibits a distinctive planar conformation [r.m.s. deviation from the mean plane of 0.009?(3)Å], and the other non-H atoms are almost coplanar [r.m.s. deviation = 0.021?(3)?Å] with the 1,4-dihydro-pyridine ring. The conformation of the latter is governed mainly by two intra-molecular C-H?O non-classical inter-actions.

Project description:In the title compound, C(21)H(27)NO(5), the dihydropyridine ring adopts a boat conformation.
