3-d]pyrimidine derivatives were synthesized by reaction of aryl-methyleneacetoacetates with different aminopyrimidines. The solid-state structure of the methyl 5-(3′-chlorophenyl)-7-methyl-4-oxo-2-thioxo-1,2,3,4,5,8-hexahydropyrido[2,3-d]pyrimidine-6-carboxylate shows that these compounds can adopt some of the most important structural features of the 1,4-dihydropyridine calcium channel blockers. The
通过使芳基-亚甲基乙酰乙酸酯与不同的氨基嘧啶反应,合成了几个系列的吡啶并[2,3-d]嘧啶衍生物。甲基5-(3'-氯苯基)-7-甲基-4-氧代-2-硫代氧代-1,2,3,4,5,8-六氢吡啶并[2,3-d]嘧啶的固态结构-6-羧酸盐表明这些化合物可以采用1,4-二氢吡啶钙通道阻滞剂的一些最重要的结构特征。通过与通常的参考化合物硝苯地平比较,提出了具有不同氨基杂环的合成方法的范围和局限性,以及它们的钙拮抗活性的初步评估。
