Abstract
A method for producing optically active alcohols is provided. Optically active alcohols are useful intermediates in pharmaceutical production. The method of the present invention enables simple and efficient production of optically active alcohols with a high optical purity. According to the production method disclosed, optically active alcohols are produced via asymmetric reduction of 3-quinuclidinone using tropinone reductase-I. For example, the use of tropinone reductase-I derived from plants likeandallows the production of high optical purity (R)-3-quinuclidinol.
