Metal-Free TEMPO-Promoted C(sp3)–H Amination To Afford Multisubstituted Benzimidazoles
摘要:
An efficient TEMPO-air/cat. TEMPO-O-2 oxidative protocol was developed to synthesize multisubstituted or fused tetracyclic benzimidazoles via a metal-free oxidative C-N coupling between the sp(3) C-H and free N-H of readily available N-1-benzyl/alkyl-1,2-phenylenediamines.
