Abstract

It is possible to produce an optically active fluoroalkyl chloromethyl alcohol with a high optical purity and a good yield by treating a fluoroalkyl chloromethyl ketone with a microorganism having an activity for asymmetrically reducing the ketone or an enzyme having the activity. Then, it is possible to obtain a fluoroalkyl ethylene oxide by treating the alcohol with a base. Industrial implementation of the production method of the present invention is easy.
