dearomatization of indoles with unactivated alkenes is described with moderate to good yields and good to excellent diastereoselectivities. Under visible-light irradiation, the photoexcited state of the palladium complex was formed, which could transfer a single electron to N-(2-bromobenzoyl)indoles, leading to a hybrid palladium radical chemistry. This provides efficient and atom-economical access to diverse
描述了一种温和的可见光驱动的钯催化的吲哚与未活化烯烃的自由基串联脱芳构化反应,具有中等至良好的产率和良好至优异的非对映选择性。在可见光照射下,钯络合物形成光激发态,可将一个电子转移到N- (2-溴苯甲酰基)吲哚上,形成杂化钯自由基化学。这提供了对各种 2,3-二取代二氢吲哚衍生物的有效和原子经济的访问。
