Oxazolidin-2-one-Promoted CuI-Catalyzed Amidation of Aryl Halides and Cyclization of o-Halobenzanilides.

Oxazolidin-2-one was found to be a versatile and efficient ligand for the CuI-catalyzed amidation of aryl halides and the cyclization of ORTHO-halobenzanilides. Notably, the less active halides could also be applied successfully in the synthesis of benzoxazoles and benzothiazoles. [ABSTRACT FROM AUTHOR]
