开发了使用烯丙基硼酸对N-叔丁烷亚磺酰基 α-亚氨基酯进行非对映选择性烯丙基化,以获得具有良好收率和非对映选择性的光学活性非蛋白原 α-氨基酸前体。革兰氏规模合成、广泛的官能团耐受性、出色的立体发散性、合成后修饰以及手性助剂的轻松去除是其中的一些关键亮点。该协议适用于各种氨基酸和短肽,导致这些前体在 N 端位置的结合。

An extremely mild and practical approach for the preparation of enantiomerically enriched beta-aryl substituted homoallylic amines bearing two adjacent stereogeniccenters was realized by room temperature zinc-mediated highlystereoselective cinnamylation of N-sulfinyl imines.
