Isoindoline derivatives of the formula ##STR1## and the pharmaceutically acceptable acid addition salts thereof, wherein R represents a moiety selected from the group consisting of hydrogen, halogen, lower alkyl, lower alkoxy, nitro, hydroxy and hydroxy lower alkyl, and n is a positive number from 1 to 3, which R's may be the same or different when n is 2 or 3, and when n is 2, the two R's may be joined to the carbon atom vicinal to the phenyl ring to which the two R's are joined and may taken together form lower alkylenedioxy and the group ##STR2## and R.sub.1 is a member of the group consisting of hydrogen and lower alkyl. The compounds of this invention can be readily prepared by reacting a compound of the formula ##STR3## wherein R represents, in addition to the above defined, alkoxycarbonyloxy; R.sub.1 and n are as defined above; and X is halogen or the groups --O--SO.sub.2 --Y where Y is either lower alkyl or aryl, with isoindoline of the formula ##STR4## or a minemal acid salt thereof. The compounds are useful in such fields as, for example cardiovascular drugs.
公式为 ##STR1## 的异吲哚啉衍生物及其药学上可接受的酸盐,其中R代表从氢、卤素、低烷基、低烷氧基、硝基、羟基和羟基低烷基所选的基团,n为1到3的正数,当n为2或3时,R可能相同或不同,当n为2时,这两个R可能连接到邻苯环的碳原子上,形成低烷基氧二氢基和 ##STR2## 基团,R.sub.1为氢和低烷基所选的基团。本发明的化合物可以通过将公式为 ##STR3## 的化合物与公式为 ##STR4## 的异吲哚啉或其最小酸盐反应而轻松制备。这些化合物在心血管药物等领域中有用。
