  摘要：

  在3-和5-位置带有羰基功能的1,4-二氢吡啶，可以在6-位置被低级烷基取代，4-位置被低级烷基、苯基、取代苯基或杂环基取代，并通过1-和2-位置与五、六或七元环烷基环融合，其中一种亚甲基基团可以被硫、氧、亚胺或烷基亚胺取代，是抗高血压药物和冠状血管扩张剂。这些化合物，其中6-甲基-4-(3-硝基苯基)-1,2-戊亚甲基-1,4-二氢吡啶-3,5-二羧酸3,5-二乙酯是一个具有代表性的实施例，可以通过酰乙酰乙酸酯和环状烯胺羰基衍生物的缩合制备。

  1,4-Dihydropyridines bearing carbonyl functions in the 3- and 5-positions, being optionally substituted by lower alkyl in the 6-position, being substituted in the 4-position by lower alkyl, phenyl, substituted phenyl or a heterocyclic group, and being fused through the 1- and 2-positions to a five, six or seven membered cycloalkyl ring, one methylene group of which can be replaced by sulfur, oxygen imino or alkylimino, are antihypertensive agents and coronary vessel dilators. The compounds, of which 6-methyl-4-(3-nitrophenyl)-1,2-pentamethylene-1,4-dihydropyridine-3,5-dica rboxylic acid 3,5-diethyl ester is a representative embodiment, are prepared through condensation of an ylideneacetoacetic acid ester and a cyclic enamino carbonyl derivative.
