초록
We report an efficient metal-free azaphosphaannulation of a myriad of phosphonamides through intramolecular oxidative C-N bond formation using Phl(OAc)(2) and iodine in acetonitrile under air, thus leading to the formation of benzazaphosphol-3-one 1-oxides, which are novel phosphorus heterocyclic privileged structures.
