delivers the desired 1,2-diarylated and 1,2-arylalkenylated products with excellent regiocontrol. To demonstrate the synthetic utility of the method, a representative product is prepared on gram scale and then diversified to eight 1,2,3-trifunctionalized building blocks using two-electron and one-electron logic. Using this method, three routes toward bioactive molecules are improved in terms of yield
据报道,镍催化链烯基羧酸,芳基碘化物和芳基/链烯基硼酸酯的交叉偶联。该反应提供所需的1,2-二芳基化和1,2-芳基烯基化的产物,具有极好的区域控制。为了证明该方法的综合实用性,以克为单位制备了代表性产品,然后使用二电子和一电子逻辑将其多样化为八个1,2,3-三官能化结构单元。使用该方法,在产率和/或步骤数方面改进了通往生物活性分子的三种途径。该方法代表由天然羧酸酯基引导的烯烃的催化1,2-二芳基化的第一个实例。
