Asymmetric Catalysis: A novel chiral bipyridine ligand with a flexible hydrogen-bond donor was developed based on the TS-stabilization concept. This designed chiral bipyridine ligand was applied to the copper-catalyzed asymmetric borylation of a wide range of α,β-unsaturated ketones, affording the borylated products in high yields with high enantioselectivities. The potential of a high-level control
不对称催化:基于 TS 稳定概念开发了一种具有柔性氢键供体的新型手性联吡啶配体。这种设计的手性联吡啶配体被应用于铜催化的各种 α,β-不饱和酮的不对称硼化反应,以高产率和高对映选择性提供硼化产物。还证明了对化学选择性和立体选择性进行高级控制的潜力。
