3-tert-Butyl 5-methyl (2R,4S,5R)-2-(4-methoxyphenyl)-4-(3-nitrophenyl)-1,3-oxazolidine-3,5-dicarboxylate
The title mol-ecule, C(23)H(26)N(2)O(8), was synthesized in three steps starting from m-nitro-cinnamic acid. The central oxazolidine ring adopts an almost perfect envelope conformation with the O atom as the flap [puckering parameter ϕ = 0.3 (6)°]. The dihedral angle formed by the benzene rings is 61.81 (9)°. In the crystal, mol-ecules are connected into double chains parallel to [010] by C-H⋯O...

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 ...

* 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...

In the title compound, C(18)H(21)NO(3), the 1,4-dihydro-pyridine ring exhibits a flattened boat conformation. The methoxy-phenyl ring is nearly planar [r.m.s. deviation = 0.0723 (1) Å] and is perpendicular to the base of the boat [dihedral angle = 88.98 (4)°]. Inter-molecular N-H⋯O and C-H⋯O hydrogen bonds exist in the crystal structure.

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.
