A novel copper/I2-mediated oxidative cross-coupling/cyclization of 2-(pyridin-2-yl)acetate derivatives and simple olefins is developed, which provides a straightforward and efficient access to structural diversely indolizines. A series of 1,3-di- and 1,2,3-trisubstituted indolizines are easily synthesized in modest to excellent yields.
开发了新颖的铜/ I 2介导的2-(吡啶-2-基)乙酸酯衍生物和简单烯烃的氧化交叉偶联/环化,其提供了直接且有效地获得结构多样的吲哚嗪的途径。一系列1,3-二-和1,2,3-三取代的吲哚嗪很容易合成,收率适中至优异。
