A benzylalcohol derivative of the formula: ##STR1## wherein R is hydroxy, benzyloxy, halogen or alkoxy having one to four carbon atoms, and Ring A is monomethoxyphenyl, dimethoxyphenyl, trimethoxyphenyl or 3,4-methylenedioxyphenyl, or a pharmaceutically acceptable acid addition salt thereof is prepared by reducing a compound of the formula: ##STR2## wherein R' is benzyloxy, halogen or alkoxy having one to four carbon atoms, and Ring A is the same as defined above, to give a compound of the formula: ##STR3## wherein R' and Ring A are the same as defined above, and when R' is benzyloxy, if required, further subjecting the compound [I'] to catalytic hydrogenation to give a compound of the formula: ##STR4## wherein Ring A is the same as defined above. The benzylalcohol derivative [I] is useful as an anti-diabetic agent.
本发明提供了一种苄基醇衍生物,其化学式为:##STR1## 其中R是羟基、苄氧基、卤素或有1至4个碳原子的烷氧基,环A是单甲氧基苯基、双甲氧基苯基、三甲氧基苯基或3,4-亚甲二氧基苯基,或其药学上可接受的酸盐。该苄基醇衍生物是通过还原化合物的公式得到的:##STR2## 其中R'是苄氧基、卤素或有1至4个碳原子的烷氧基,环A与上述定义相同,以得到化合物的公式:##STR3## 其中R'和环A与上述定义相同,当R'是苄氧基时,如有必要,进一步将化合物[I']进行催化加氢,以得到化合物的公式:##STR4## 其中环A与上述定义相同。苄基醇衍生物[I]作为一种抗糖尿病药物具有应用价值。
