1-(3-Chlorophenyl)ethanone → (1S)-1-(3-CHLOROPHENYL)ETHANOL

Participants

Reaction Steps

To a solution of borane-tetrahydrofuran (77.6 mL, 77.62 mmol, Aldrich, 1 M solution in THF) and (R)-MeCBS (12.9 mL, 12.9 mmol, Aldrich, 1M solution in toluene) was added a solution of 3-chloroacetophenone (20.0 g, 129.37 mmol) in anhydrous tetrahydrofuran slowly over 30 min at room temperature. After complete addition, the reaction mixture was stirred for 10 min, quenched with 2N hydrochloric acid over 30 min. The reaction mixture was extracted with ether, dried, filtered and concentrated to afford 20.8 g of (S)-1-(3-chlorophenyl)ethanol as a viscous liquid.
