By design: A series of α‐acetoxy‐β‐enamino esters 1 were synthesized and then subjected to catalytic asymmetric hydrosilylation. In the presence of a chiral Lewis base catalyst, the reactions proceeded smoothly to provide a wide range of chiral α‐acetoxy β‐amino acid derivatives in high yields with good diastereoselectivities and enantioselectivities.
通过设计:合成了一系列α-乙酰氧基-β-烯氨基酯1,然后进行催化不对称氢化硅烷化。在手性路易斯碱催化剂的存在下,反应顺利进行,以高收率提供了多种手性α-乙酰氧基β-氨基酸衍生物,具有良好的非对映选择性和对映选择性。
