A variety of chiral β-hydroxy-α-amino acids and derivatives thereof can be synthesized enantioselectively using the aldol reaction of an aldehyde, the glycinate 1 and the cinchonidine-derived catalyst 2, as indicated in Schemes 1 and 2 and Table 1.
如方案1和2以及表1所示,使用醛,甘氨酸盐1和辛可尼定衍生的催化剂2的醛醇缩合反应可以对映选择性地合成多种手性β-羟基-α-氨基酸及其衍生物。
