Several omega -bromoacetophenone derivatives 6a-f were reduced to (R)-(-)-2
-bromo-1-(phenyl/substituted phenyl) ethanol derivatives 7a-f with whole ce
ll biocatalysts in good yields. The enantiomeric excesses were increased to
95% using an anionic surfactant under an inert atmosphere in an aqueous me
