simple ether-directed iridium-catalyzed site- and enantioselective C(sp2)-H borylation of benzhydryl ethers for the first time. Various chiral benzhydryl ethers were obtained with high enantioselectivities in the presence of a tailor-made chiral bidentate boryl ligand. We found that the kinetic resolution relay significantly amplified the enantioselectivity. The synthetic utility of the current method was
我们在此首次报道了二苯甲基醚的简单醚导向铱催化位点和对映选择性 C(sp 2 )-H 硼基化反应。在特制的手性二齿硼基配体存在下,获得了具有高对映选择性的各种手性二苯甲基醚。我们发现动力学拆分中继显着增强了对映选择性。当前方法的合成效用通过克级CH硼化和CB键转化得到了证明。
