Copper-Catalyzed Three-Component Carboamination of Arynes: Expeditious Synthesis of o‑Alkynyl Anilines and o‑Benzoxazolyl Anilines

A copper-catalyzed three-component reaction of in situ formed arynes, terminal alkynes, and O-benzoyl­hydroxyl­amines has been developed. By adjusting reaction conditions, the nucleophiles in this transformation can be extended from terminal alkynes to benzoxazoles. These procedures provide a modula...
