从易得原料D-苯甘氨酸出发,经酯化、N-烷基化及还原等三步反应合成了五个手性β-氨基醇5和6.以此为手性配体,对催化芳香醛的不对称烯丙基化反应进行了初步研究,显示了中等程度的立体选择性.
Chiral β-amino alcohols 5 and 6 were prepared efficiently from D-phenylglycine through esterification,N-alkylation and reduction reactions.By using these compounds as the chiral ligand,preliminary study on asymmetric allylation reactions of aromatic aldehyde was carried out,in which the moderate enantioselectivities were achieved.
