Two β-aminoalcohols possessingbulky substituents on the carbon atom with the hydroxyl group were readily synthesized from L-proline, and used as chiral ligands for catalytic asymmetricaddition of diethyl zinc to arylaldehydes. The resultant second alcohols withS configuration as well as good to higher ee values were achieved. The results showed that much bulkier substituents could not induce higher enantioselectivity.

Key words: β-aminoalcohol, asymmetric addition, carbonyl compound, chiral alcohol
