Three novel sulfur-containing chiral β-amino alcohols 4a - 4c have been prepared from S-alkylated L-cysteine 2a - 2c. These compounds could be used as catalysts in the enantioselective reduction of prochiral ketones with the NaBH_4/I_2 system. The optically active secondary alcohols were obtained in moderate to high enantiomeric excesses and high chemical yields.
