carbene catalysis was developed. The Lewis acidic P center simultaneously activate the bonded formyl group and stabilize the conformation of Breslow intermediates, it may help to achieve high stereo and regio-selectivities. Following the oxidation of the Breslow intermediate, nucleophile facilitates recycling of NHC to generate enantioenriched trivalent phosphorus compounds.
开发了一种结合分子内 PnB 相互作用和卡宾催化不对称合成手性 P III化合物的催化方法。 Lewis酸性P中心同时激活键合的甲酰基并稳定Breslow中间体的构象,可能有助于实现高立体和区域选择性。 Breslow 中间体氧化后,亲核试剂促进 NHC 的再循环,生成对映体富集的三价磷化合物。
