This dual catalytic regime exhibited high efficiency and good functional group compacity. A wide variety of substrates bearing a diverse set of functional groups could be converted into chiral phosphates in good to excellent yields and enantioselectivities. The utility of the method was also demonstrated by the development of a new phosphine ligand and the synthesis of enzyme inhibitor derivatives
手性含膦骨架是生物活性天然产物、药物、手性催化剂和配体中的重要基序。在此,我们报告了一个通用的模块化平台,通过 α-溴磷酸盐和芳基碘化物之间的 Ni/光氧化还原催化的对映收敛还原交叉偶联来获得手性 α-芳基磷化合物。这种双重催化方案表现出高效率和良好的官能团紧密性。具有多种官能团的多种底物可以转化为手性磷酸盐,具有良好的产率和对映选择性。新膦配体的开发和酶抑制剂衍生物的合成也证明了该方法的实用性。
