Chemical oxidation of (−)-bornyl acetate provides a mixture of 3-, 5-, and 6-oxobornyl acetate, whereas microbiological hydroxylation with cultures of Helminthosporiumsativum gives a mixture of 2,3-, 2,6-, and 2,5-bornanediols. In each case the reaction occurs preferentially at the C(5) position. Microbiological hydroxylation of (+)-bornyl acetate with H. sativum occurs almost exclusively at the C(5)
(-)-醋酸冰片酯的化学氧化提供了 3-、5- 和 6- 氧代冰片酯的混合物,而用蠕孢菌培养物进行的微生物羟基化产生了 2,3-、2,6- 和 2,5 的混合物-冰片二醇。在每种情况下,反应优先发生在 C(5) 位置。(+)-醋酸冰片与 H. sativum 的微生物羟基化几乎完全发生在 C(5) 位置。(+)- 或 (-)- 醋酸冰片与 Fusariumculmorum 培养物的区域特异性羟基化也发生在 C(5) 位置,但不会伴随乙酰氧基水解。
