Calcium antagonists of the formula ##STR1## with R(1), R(2), R(3) and R(4) being, inter alia, H, alkyl, alkoxy, halogen, in some cases phenyl; m being 1-4; n being 0-3; X being CH.sub.2, O, S, CO, CHOH or CR.sub.2, and R(5) being various groups containing nitrogen atoms, are described. They are obtained by reaction of compounds II which are likewise new and which contain in place of R(5) a leaving group Y (Cl, Br, I) with the appropriate (cyclic) amino compound. Another synthesis comprises reaction of the appropriate indollinone derivative IV which has a non-etherified hydroxyl group with a side chain which contains a terminal leaving group Z (Cl, Br, I) in the presence of a base. Furthermore, indolinone derivatives VI with an ether side chain with a terminal epoxide group can be reacted with (cyclic) amines to give compounds I.
描述了一种公式为## STR1 ##的钙拮抗剂,其中R(1),R(2),R(3)和R(4)是H,烷基,烷氧基,卤素,有时是苯基; m为1-4; n为0-3; X为CH.sub.2,O,S,CO,CHOH或CR.sub.2,R(5)为含氮基团的各种基团。它们是通过与相应的(环)氨基化合物反应获得的,该化合物II同样是新的,其中在R(5)的位置上含有离去基团Y(Cl,Br,I)。另一种合成方法包括在碱存在下,将具有非醚化羟基的适当吲哚酮衍生物IV与含有末端离去基团Z(Cl,Br,I)的侧链反应。此外,具有含有末端环氧基的醚侧链的吲哚酮衍生物VI可以与(环)胺反应以得到化合物I。
