A novel method for the synthesis of chiral β3-amino acids is developed where the acid functionality was built by oxidative cleavage of an α-allylic group that was introduced by Evans’ asymmetric alkylation of an appropriate acid substrate and the amino part came from the amide of the original carboxyl group following a modified Hofmann rearrangement reaction.
开发了一种合成手性β3-氨基酸的新方法,其中酸功能团是通过氧化断裂引入的α-烯丙基,该基团由Evans不对称烷基化适当的酸底物引入,而氨基部分则来自原始羧基的酰胺,经过改良的Hofmann重排反应后形成。
