中文摘要：
手性β-氨基醇是不对称催化反应中应用最为广泛的手性配体之一.以L-苯丙氨酸为原料简捷合成的手性β-氨基醇L＊为手性配体,对不同取代芳香醛的对映选择性炔化反应进行了研究,结果表明其对该反应具有一定的不对称催化活性,光学收率（e.e值）最高达78.9%.
英文摘要：
Chiral amino alcohols are one of the most widely employed types of ligands for asymmetric catalysis.In this paper,the easily prepared chiral tertiary amino alcohol L＊,which was derived from L-phenylalanine,was found to catalyze the reaction of alkynylzinc reagents with various aldehydes to generate chiral propargylic alcohols with moderate-to-good enantioselectivities up to 78.9% e.e.
