A process for producing an optically active halogen-containing alcohol having a high optical purity and represented by the following formula [I]
wherein R1 is a halogen substituted alkyl group, R2 is a group selected from the group consisting of a substituted or unsubstituted alkyl group, alkene group, or alkyne group, and a substituted or unsubstituted phenyl group, and C having an asterisk indicates an asymmetric atom,
is disclosed which process comprises subjecting a halogenated alkyl ester of a carboxylic acid represented by the following formula [II]
wherein R1 and R2 are the same as mentioned above and R3 is a group selected from the group consisting of a substituted or unsubstituted alkyl group or alkene group, and a substituted or unsabstituted phenyl group,
to asymmetric hydrolysis with an enzyme in an aqueous solution system, and the aqueous solution system may contain buffer solution and/or organic solvent.
