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 indolinone 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.
描述了一种化学公式为##STR1##的钙拮抗剂,其中R(1)、R(2)、R(3)和R(4)为H、烷基、烷氧基、卤素,有时为苯基;m为1-4;n为0-3;X为CH.sub.2、O、S、CO、CHOH或CR.sub.2,R(5)为含氮原子的各种基团。它们通过化合物II的反应获得,这些化合物同样是新化合物,其中R(5)的位置含有一个离去基团Y(Cl、Br、I),并与适当的(环状)氨基化合物发生反应。另一种合成方法包括将具有未醚化羟基的适当吲哚酮衍生物IV与含有终端离去基团Z(Cl、Br、I)的侧链在碱存在下反应。此外,具有含有终端环氧基团的醚侧链的吲哚酮衍生物VI可与(环状)胺反应,得到化合物I。
