chiral Schiff bases have been prepared in good yields from various carbonyl groups and two 2-amino alcohols. LiAlH4 was treated with different equivalents of the Schiff bases. Enantioselective reduction of acetophenone is achieved in high chemical yield (up to 93%) with moderate enantiomeric excess (up to 22%) by use of the new reducing agents.
