Norstatine and its analogs, i.e., 3-amino-2-hydroxyalkanoic acids, with high enantiomeric purity are obtained through effecient asymmetric synthesis of 3-silyloxy-β-lactams by chiral enolate - imine cyclocondensation, followed by hydrolysis.
通过手性烯醇化物-亚胺环缩合,然后水解,有效地不对称合成3-甲硅烷氧基-β-内酰胺,可以得到具有高对映体纯度的Norstatine及其类似物,即3-氨基-2-羟基链烷酸。
