An iridium-catalyzed enantioconvergent coupling of the versatile boron-stabilized organozinc reagent BpinCH2ZnI with a racemic branched allylic carbonate has been developed here, which differs from our previous work by using 1,1-bisborylmethane through the kinetic resolution process. The reaction has a broad substrate scope, and various chiral homoallylic organoboronic esters could be obtained in good
在这里开发了一种铱催化的对映聚合偶联的多功能硼稳定有机锌试剂 BpinCH 2 ZnI 与外消旋支链烯丙基碳酸酯,这与我们之前的工作不同,它通过动力学拆分过程使用 1,1-双硼基甲烷。该反应具有广泛的底物范围,可以以良好的收率和优异的对映选择性获得各种手性高烯丙基有机硼酸酯。这些产品的合成实用性通过将它们转化为其他有用的化合物家族来证明。
