A process for the preparation of a two-functional-group-containing terpenoid having the general formula: ##STR1## in which n is an integer of from 1 to 5, R represents a hydroxymethyl, formyl or carboxyl group, and A represents the hydrogen atom, or a 2-tetrahydropyranyl, benzyl, methoxymethol or methoxyethoxymethyl group comprising the oxidation with a microorganism belonging to the genus Nocardia. Some of the terpenoids are of value as anti-ulcer agents, while others are useful as intermediates.
一种制备含有两个功能基团的
萜类化合物的方法,其通式为:##STR1## 其中n为1到5的整数,R代表羟甲基、甲酰基或羧基,A代表氢原子或2-
四氢吡喃基、苄基、甲氧
甲醇基或甲氧乙氧甲基基团。该方法涉及使用属于诺卡氏菌属微
生物的氧化反应。其中一些
萜类化合物可作为抗溃疡剂,而另一些则可作为中间体。
