A compound having the formula: ##STR1## wherein Ring A is monohydroxyphenyl, or a pharmaceutically acceptable acid addition salt thereof is prepared by catalytic hydrogenation of a compound having the formula: ##STR2## wherein A' is monobenzyloxyphenyl, and Y is carbonyl or hydroxymethylene. The compound (I) in which Ring A is 4-hydroxyphenyl or 3-hydroxyphenyl is useful as a cardiotonic agent. On the other hand, the compound (I) in which Ring A is 2-hydroxyphenyl is useful as an anti-diabetic agent.
具有以下结构式的化合物:##STR1## 其中环A为单羟基苯基,或其药用可接受酸盐是通过对具有以下结构式的化合物进行催化氢化制备的:##STR2## 其中A'为单苄氧苯基,Y为羰基或羟甲基。环A为4-羟基苯基或3-羟基苯基的化合物(I)可用作强心剂。另一方面,环A为2-羟基苯基的化合物(I)可用作抗糖尿病剂。
