The enantioselective synthesis of fluoxetine hydrochloride, a potent serotonin-uptake inhibitor, was described. The asymmetric reduction of 3-chloropropiophenone catalyzed by chiral oxazaborolidines enantioselectively gave S- or R-3-chloro-1-phenylpropanol (2) in good yield. In following two steps, alcohol 2 was converted into S- or R-fluoxetine hydrochloride in 66.5% overall yield and 98.6% ee. Some factor effecting the yield and the enantioselectivity of asymmetric reduction of 3-chloropropiophenone was investigated.

Key words: fluoxetine hydrochloride, chiral oxazaborolidine, asymmetric reduction, inhibitor
