in modern organic synthesis, and they are usually obtained by the borylation of alkynes. We report herein highly regio- and stereoselective syntheses of α,Z- and β,Z-trifluoromethylated alkenylboranes by copper-catalyzed borylation reactions. Further functionalizations by palladium-catalyzed Suzuki–Miyaura cross-couplings have been developed and, interestingly, a marked difference in reactivity between
烯基硼烷是现代有机合成的关键中间体,通常通过炔烃的硼基化获得。我们在此报道了通过铜催化的硼化反应高度区域和立体选择性合成α, Z-和β,Z-三氟甲基化烯基硼烷。钯催化的 Suzuki-Miyaura 交叉偶联的进一步功能化已经得到开发,有趣的是,α- 和 β- 硼化异构体之间的反应性存在显着差异。
