Rh(III)-Catalyzed C–H Amidation with N-Hydroxycarbamates: A New Entry to N-Carbamate-Protected Arylamines
摘要:
An unprecedented Rh(III)-catalyzed direct intermolecular C-H amidation with N-hydroxycarbamates has been developed. Different directing groups, such as pyridine, pyrimidine, pyrazole, and N-OMe oxime, can be employed in this C-H amidation process, providing valuable N-carbamate-protected arylamines (e.g., Cbz, Moz, Ac, Boc, and Fmoc). More importantly, this process may afford a new avenue for intermolecular C-H amidation where readily available N-hydroxycarbamates can be used as the nitrogen source
