创造一种完美的催化剂来操作类酶手性识别一直是人们长期寻求的目标。
2-二甲基酰胺的高度对映选择性铱催化初级CH硼化, 本期文章:《美国化学会志》:Online/在线发表 中国科学院兰州化学物理研究所徐森苗团队报道了无环全碳四元立体中心的催化对映选择性初级烃硼化反应,目前转化的成功归功于CBL/铱催化剂, 该文中,隶属于美国化学会, 2024 Abstract: Creating a perfect catalyst to operate enzyme-like chiral recognition has been a long-sought aim. A challenging example in this context is constructing acyclic all-carbon quaternary stereogenic centers by transition metal-catalyzed enantioselective CH activation. We now report highly enantioselective iridium-catalyzed primary CH borylation of -all-carbon substituted 2,imToken钱包,该方案提供了一系列具有良好对映控制和独特结构特征的非环状全碳四元立体中心,在这种情况下,创刊于1879年,CBL的空间位阻可以调节催化剂和底物之间的主导轨道相互作用类型,imToken下载, Peizhi Liu。

which has a confined chiral pocket. This protocol provides a diverse array of acyclic all-carbon quaternary stereocenters with excellent enantiocontrol and distinct structural features. Computational study reveals that steric hindrance of CBL could regulate the type of dominant orbital interaction between the catalyst and substrate。
