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代表酰基,X代表氧或可选的取代亚胺基,A代表被--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代表氧,而不是氧的基团X.sub.1或X.sub.2代表直接键,Ph代表可选的取代苯基基团,R代表可选的取代苯基、吡啶基或1-氧代吡啶基、(1,3-二氧杂)吲哚基或苯并呋喃基团,R.sub.1代表可选的取代苯基或吲哚基团,R.sub.2代表脂肪烃基团,R.sub.3代表脂肪基、氰基或氨基,以及其酸加成盐。
