Using cheap and readily accessible CuCl as the catalyst, an operationally simple and efficient method for the synthesis of 3,5-disubstituted oxazolones has been realized by the cyclization of N-alkynyl tert-butyl carbamates. The reaction proceeds under mild reaction conditions and shows good functional group compatibility.
