Abstract
A process for preparing optically active 2-halo-1-phenyl ethanol having the general formula [I*]: ##STR1## wherein X is a halogen atom, by asymmetrically reducing 2-halo-acetophenone having the general formula [II]: ##STR2## wherein X is as above, to give optically active 2-halo-1-phenyl ethanol, (R)-form or (S)-form, employing the microorganism. ##STR3## According to the present invention, optically active 2-halo-1-phenyl ethanol can be prepared with a good optical purity and yield in a simple process.
