Abstract
Both enantiomers of optically active 2-alkanol are produced by transesterification reaction of racemic 2-alkanol and aliphatic acid 2,2,2-trichloroethylester in the presence of enzyme derived from Candida antarctica. Both enantiomers of optically active 2-alkanol, which are useful as starting materials of liquid crystal materials and have optical purity of 99% or more, can be efficiently produced.
