N‐allylindoles by a one‐pot Ir‐catalyzed asymmetric allylic alkylation/oxidation reaction of indolines has been realized. The current method features high regioselectivity and enantioselectivity together with a broad range of indoles with varying electronic properties. The utility of this method was demonstrated by the synthesis of dihydropyrrolo[1,2‐a]indole derivatives.
有两个步骤可能比一个步骤更好:通过一锅Ir催化的二氢吲哚的不对称烯丙基烷基化/氧化反应,可以有效地合成对映体富集的N-烯丙基。目前的方法具有很高的区域选择性和对映选择性,以及范围广泛的具有不同电子特性的吲哚。通过合成二氢吡咯并[1,2- a ]吲哚衍生物证明了该方法的实用性。
