The first Ni-catalyzed Suzuki–Miyaura coupling of alkyl halides with alkenyl-(9-BBN) reagents is reported. Both primary and secondary alkyl halides including alkyl chlorides can be coupled. The coupling method can be combined with hydroboration of terminal alkynes, allowing the expedited synthesis of functionalized alkyl alkenes from readily available alkynes with complete (E)-selectivity in one pot
据报道,烷基卤化物与烯基-(9-BBN)试剂的首次Ni催化的Suzuki-Miyaura偶联反应。包括烷基氯化物的伯烷基卤和仲烷基卤都可以偶联。该偶联方法可以与末端炔烃的硼氢化反应结合使用,从而允许在一个反应釜中从容易获得的炔烃以完全的(E)选择性加速合成官能化的烷基烯烃。该方法用于天然大环内酯(±)-瑞奇奥利特的全合成。
