New symmetrical 4-[2-chloro-2-(4-chloro-6-methyl-2-oxo-2H-pyran-3-yl)vinyl]-substituted 1,4-di-hydropyridines were synthesized in moderate to good yields via the modified Hantzsch reaction of β-dicarbonyl compounds with (Z)-3-chloro-3-(4-chloro-6-methyl-2-oxo-2H-pyran-3-yl)acrolein in the presence of an excess amount of NH4OAc. Also, the reaction of β-dicarbonyl compounds with (Z)-3-chloro-3-(4-ch
以中等到良好的产率合成了新的对称的4- [2-氯-2-(4-氯-6-甲基-2-氧代-2H-吡喃-3-基)乙烯基]取代的1,4-二氢吡啶过量存在下,通过β-二羰基化合物与(Z)-3-氯-3-(4-氯-6-甲基-2-氧代-2H-吡喃-3-基)丙烯醛的改良汉兹反应NH 4 OAc。同样,β-二羰基化合物与(Z)在存在氨基酯和酮的条件下进行)-3-氯-3-(4-氯-6-甲基-2-氧代-2-H-吡喃-3-基)丙烯醛和不对称的4- [2-氯-在室温下以中等至良好的产率获得2-(4-氯-6-甲基-2-氧代-2-H-吡喃-3-基)乙烯基]-取代的1,4-二氢吡啶。评估了这些化合物的钙通道阻断活性。尽管一种化合物相对于参考药物硝苯地平具有类似的作用(IC 50 = 1.40×10 -7 M),但它们显示出中度至微弱的作用。
