Abstract
The problem to be resolved by the present invention is to provide a method for efficiently synthesizing optically active lower aliphatic alcohols that have difficulty in separation from organic solvents, without using a special reactor. The present invention relates to a method for producing an optically active aliphatic alcohol having a fluorine atom at α position, wherein an optically active alcohol is produced by reacting an aliphatic ketone having a fluorine atom at α position in water using a formate, under the presence of an asymmetric catalyst represented by general formula (1) and an acid.
