An efficient method for C7‐position‐selective alkenylation of N‐substituted indolines with alkenes is reported. Various 7‐alkenylindolines were obtained in moderate to excellent yields in air in the presence of catalytic amounts of [Cp*IrCl2]2, AgOTf, and Cu(OAc)2. The protocol relies on the use of a carbonyl or carbamoyl group on the nitrogen atom of indoline as a directing group and is potentially
报道了一种有效的方法,用于用烯烃对N取代的二氢吲哚进行C7位置选择性烯基化。在催化量的[Cp * IrCl 2 ] 2,AgOTf和Cu(OAc)2的存在下,在空气中以中等至优异的产率获得了各种7-烯基二氢吲哚。该方案依赖于在吲哚啉氮原子上使用羰基或氨基甲酰基作为导向基团,并且可能适用于7-烯基吲哚和7-烷基吲哚的合成。
