发明名称 2,3,5,6-Tetracarboxy-4-pyridyl-1,4-dihydropyridine derivatives
摘要 1,4-Dihydropyridines bearing carboxy functions in the 3-, 5- and 6- or 2-, 3-, 5- and 6-positions and being substituted in the 4-position by phenyl, substituted phenyl, naphthyl, phenylalkyl or a heterocyclic group are antihypertensive agents and coronary vessel dilators. The compounds, of which 2-methyl-4-(3-nitrophenyl)-1,4-dihydropyridine-3,5,6-tricarboxylic acid triethylester is a representative embodiment, are prepared through condensation of an enamine with an ylidene acid ester, the latter being separately prepared or prepared in situ.
