Hydrolysis of 3,7-diacetoxycycloheptene using electric eel acetylcholinesterase gives optically pure (3R,7S)-3-hydroxy-7-acetoxycycloheptene, and hydrolysis using lipase enzyme from Candida cyclindracea gives the same hydroxy acetate, but in only 44% enantiomeric excess, in contrast to the normal behaviour of lipase which gives (S) alcohols for related hydrolyses; 3,7-diacetoxy-4,6-dimethylcycloheptene
使用鳗鱼乙酰胆碱酯酶水解3,7-二乙酰氧基环庚烯可得到光学纯的(3 R,7 S)-3-羟基-7-乙酰氧基环庚烯,使用来自假丝酵母的脂肪酶水解可得到相同的羟基乙酸酯,但对映异构体仅为44%与脂肪酶的正常行为相反,脂肪酶的正常行为会产生(S)醇进行相关水解;3,7-二乙酰氧基-4,6-二甲基环庚烯(10)不被乙酰胆碱酯酶水解,但很容易被脂肪酶水解,得到(3 S,4 R,6 S,7 R)-3-羟基-7-乙酰氧基- 4,6-二甲基环庚烯。
