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。
aromatic amines in the presence of aliphaticamines. The method is general for the preparation of mono-N-Boc, -N-Cbz, -N-Fmoc or -N-Alloc aromatic amines in high yield without affecting the aliphaticamines. This approach is applicable to substituted (aminoalkyl)aniline compounds with different functionalities and was employed to supply gram quantities of the protected aniline product. amines - carbamates
