Dimethyl 4-(4-ethoxy­phen­yl)-2,6-dimethyl-1,4-dihydro­pyridine-3,5-dicarboxyl­ate

In the title mol-ecule, C(19)H(23)NO(5), the dihedral angle formed by the benzene ring and the planar part of the dihydro-pyridine ring is 83.52 (5)°. The dihydro-pyridine ring adopts a flattened boat conformation. In the crystal, mol-ecules are linked by N-H⋯O hydrogen bonds, generating chains running parallel to [100]. The crystal structure is consolidated by C-H⋯O contacts.

Dimethyl 4-(4-hy­droxy­phen­yl)-2,6-dimethyl-1,4-dihydro­pyridine-3,5-dicarboxyl­ate

The title mol-ecule, C(17)H(19)NO(5), was prepared by a Hantzsch dihydro-pyridine synthesis from 4-hy-droxy-benzaldehyde, methyl acetoacetate and NH(4)HCO(3). In the mol-ecular structure of the title compound, the dihydro-pyridine ring adopts a flattened boat conformation and the plane of the base of the boat forms a dihedral angle of 80.8 (2)° with the aromatic six-membered ring. The packing i...

Dimethyl 2,6-dimethyl-4-phenyl­pyridine-3,5-dicarboxyl­ate

In the title compound, C(17)H(17)NO(4), the dihedral angle between the benzene and pyridine rings is 75.51 (4)°. The benzene and pyridine rings are both approximately planar (r.m.s. deviations of 0.0040 and 0.0083 Å, respectively), indicating that the pyridine N atom is not protonated. The crystal structure is stabilized by weak inter-molecular C-H⋯O and C-H⋯N inter-actions.

Different procedures for the syntheses of the title compounds were investigated. The best method for the preparation of the title compounds were the reaction of the readily available 2-formyL-1-methyl-5-nitroimidazole2- substituted-4-formylthiazoles with alkyl acetoacetate and alkyl aminocrotonate in boiling alcohol.

* email: [email protected] Nifedipine (3,5-dimethyl 2,6-dimethyl-4-(2-nitrophenyl)1,4-dihydropyridine-3,5-dicarboxylate) was developed by the German pharmaceutical company Bayer, most initial studies being performed in the early 1970s. The use of nifedipine and related calcium channel antagonists was much reduced in response to 1995 trials that mortality was increased in patients with cor...
