L-脯氨酸为起始原料,两个在其羟基所在的α-C上具有大体积取代基的β-氨基醇配体被简便地合成出来,并被用于催化二乙基锌对醛的不对称加成,得到了ee值较高的S构型的手性二级醇.结果显示更大体积取代基团的氨基醇配体并不能够获得更高的对映选择性.

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.
