Preparation of anthranils via chemoselective oxidative radical cyclization of 3-(2-azidoaryl) substituted propargyl alcohols

In presence of K₂S₂O₈ and HOAc, propargyl alcohols can go oxidative radical cyclizations to give a pool of anthranils. Excellent chemoselectivity was seen, and the synthesized anthranils can be employed as N-nucleophiles in various transformations.
