ABSTRACT:
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 anti-hypertensive 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.
