ortho-selective C–H functionalization has been developed using Cbz-amide as the directing group and Ir(III) as the catalyst. Various substrates were well tolerated, affording the corresponding products in moderate to good yields. Moreover, preliminary mechanistic study revealed the role of the amide as the coordination center to cooperate with the Ir(III) complex during C–H activation. Development of
通过使用Cbz-酰胺作为导向基团和Ir(III)作为催化剂,已经开发了一种通过邻位选择性C–H官能化合成邻位炔基化芳基烷基胺的便捷实用方法。各种底物具有良好的耐受性,以中等至良好的产率提供了相应的产物。此外,初步的机理研究揭示了酰胺在C–H活化过程中作为与Ir(III)配合物协同作用的配位中心的作用。这种由Cbz-酰胺促进的C Ar -H官能化的开发提供了一种实用的方法,在有机合成中具有潜在的应用前景。
