The invention relates to novel 1,4-dihydropyridine-3-carboxylic acid phenoxyaliphatylphenyleneoxyalkyl esters of the formula ##STR1## in which Ac represents an acyl group, X represents oxy or optionally substituted imino, A represents a divalent aliphatic hydrocarbon radical interrupted by a group --X.sub.1 --Ph--X.sub.2 -- in which at least one of the radicals X.sub.1 and X.sub.2 represents oxy and a radical X.sub.1 or X.sub.2 that is other than oxy represents a direct bond, and Ph represents an optionally substituted phenylene radical, and R represents an optionally substituted phenyl, pyridyl or 1-oxidopyridyl, (1,3-dioxa)indanyl or benzofurazanyl radical, R.sub.1 represents an optionally substituted phenyl or indolyl radical, R.sub.2 represents an aliphatic hydrocarbon radical and R.sub.3 represents an aliphatic radical, cyano or amino, and acid addition salts thereof.
本发明涉及一种新型的1,4-二氢吡啶-3-羧酸苯氧基脂肪基苯氧基烷酯,其化学式为 ##STR1## 其中Ac表示酰基,X表示氧或可选取代的亚胺基,A表示被--X.sub.1 --Ph--X.sub.2 --所中断的二价脂肪烃基,其中至少一个基团X.sub.1和X.sub.2表示氧,一个不是氧的基团X.sub.1或X.sub.2表示直接键,Ph表示可选取代的苯基基团,R表示可选取代的苯基、吡啶基、1-氧代吡啶基、(1,3-二氧杂)茚基或苯并呋喃基团,R.sub.1表示可选取代的苯基或吲哚基团,R.sub.2表示脂肪烃基团,R.sub.3表示脂肪基、氰基或氨基,以及其酸加合物盐。
