selective functionalization of relatively simple and readily accessible precursors to produce highly functionalized alkyl boronates is a synthetically useful process. Herein we report a NiH-catalyzed remote hydroarylation process that can, through a synergistic combination of chain walking and subsequent cross-coupling, introduce an aryl group at the adjacent carbon atom of alkyl boronates under mild
相对简单且容易获得的前体的直接和选择性官能化以产生高度官能化的硼酸烷基酯是合成上有用的方法。本文中,我们报道了NiH催化的远程氢芳构化过程,该过程可以通过链走和随后的交叉偶联的协同组合,在温和的条件下在烷基硼酸酯的相邻碳原子上引入芳基。通过具有中等对映选择性的初步实验,表明还可以实现不对称形式。
