The one-pot one-step synthetic method of 4H-3,1-benzoxazin-4-ones via the gold-catalyzed oxidative rearrangement of 2-alkynyl arylazides has been developed. The desired products were obtained in moderate to excellent yields under mild reaction conditions. In most cases, using acetic acid as solvent the reactions were shown to proceed very fast within 1 h.

Key words: gold-catalyzed, oxidative rearrangement, one-pot, 2-alkynyl arylazides
