copper and chiral nitroxide co-catalyzed aerobic enantioselective oxidation process has been developed that allows access to axially chiral molecules. Two complementary atroposelective approaches, oxidative kinetic resolution (OKR) and desymmetrization, were studied using ambient air as the stoichiometric terminal oxidant. OKR of rac-N-arylpyrrole alcohols and rac-biaryl alcohols affords the optically
开发了铜和手性硝基氧共催化的有氧对映选择性氧化过程,可以得到轴向手性分子。使用环境空气作为化学计量末端氧化剂,研究了两种互补的肌选择性方法,即氧化动力学解析(OKR)和去对称化。外消旋-N-芳基吡咯醇和外消旋-二芳基醇的OKR分别提供了er高达3.5:96.5和5.5:94.5的光学纯化合物。前手性二醇的去对称化提供了er高达 99:1 的轴向手性联芳基化合物。
