An efficient method for the construction of Csp2–Csp3 bond in a regio- and stereoselective fashion involving 1,3-terminal dienes, enol triflates/nonaflates, and sodium formate under Pd(0)-catalysis is described. The three component assembly allows trapping of a π-allyl intermediate, after the initial migratory insertion of the diene, by a hydride source that leads to structurally complex and synthetically
描述了一种以区域和立体选择性方式构建 Csp2-Csp3 键的有效方法,涉及 1,3-末端二烯、烯醇三氟甲磺酸酯/九氟甲磺酸酯和甲酸钠在 Pd(0) 催化下。三组分组件允许在二烯的初始迁移插入之后通过氢化物源捕获 π-烯丙基中间体,这导致结构复杂且合成上具有挑战性的三取代和四取代烯烃结构单元。
