The catalytic asymmetric amination reaction of 3-bromooxindoles with indolines for the construction of the N1–C3 linkage stereogenic centers has been realized for the first time. Moreover, the racemic substrates (3-substituted indolines) were also applicable under the same chiral conditions. The newly developed method conveniently led to a formal synthesis of (+)-psychotrimine.
首次实现了3-溴代吲哚与二氢吲哚的催化不对称胺化反应,用于构建N1-C3键构立体中心。此外,外消旋底物(3-取代的二氢吲哚)也可在相同的手性条件下使用。新开发的方法方便地导致了(+)-精神三胺的正式合成。
