An R-configuration or S-configuration optically active secondary alcohol of the general formula (1),
CH3C*H(OH)(CH2)mOCH(CnH2n+1)2 (1)
wherein C* is an asymmetric carbon atom, m is an integer of 1 to 3, and n is an integer of 1 to 3, and a process for the production thereof, comprising optical resolution of a corresponding racemic alcohol by asymmetric trans-esterification, specifically using a lipase derived from Candida antarcia microorganism.
The present invention can provide the novel optically active secondary alcohol having a methyl group on an asymmetric carbon and an alkoxy terminal having branched alkyl chains formed of the same numbers of carbon atoms, and an economical and simple process for the production thereof.
通式(1)的 R 构型或 S 构型光学活性仲醇、
CH3C*H(OH)(CH2)mOCH(CnH2n+1)2 (1)
其中,C*为不对称碳原子,m为1至3的整数,n为1至3的整数,以及其生产工艺,包括通过不对称反酯化作用对相应的外消旋醇进行光学解析,特别是使用从白色念珠菌微生物中提取的脂肪酶。
本发明可提供新型光学活性仲醇,其甲基位于不对称碳上,烷氧基末端具有由相同数量碳原子形成的支化烷基链,还可提供经济、简单的生产工艺。
