The first Pd-catalyzed multicomponent reaction of aryl iodides, alkenyl bromides, and strained alkenes has been developed, which allowed us to synthesize a variety of multisubsituted olefins in yields of 45–96% with excellent stereoselectivity. The configuration of the product was controlled by the configuration of the alkenyl bromides. Moreover, this practical methodology employing readily available
已经开发出第一个钯催化的芳基碘化物,烯基溴化物和应变烯烃的多组分反应,这使我们能够以45-96%的产率合成多种多元取代的烯烃,并具有出色的立体选择性。产物的构型由烯基溴化物的构型控制。此外,发现使用容易获得的底物的这种实用方法对多种官能团具有耐受性。通过这种方法已经成功地合成了五十六个高度立体选择性的三或四取代烯烃的例子。大多数合成的四取代烯烃都是良好的聚集诱导发射(AIE)发光剂。
