An I-2-promoted sp(3) C-H functionalization has been developed for the synthesis of 2,5-disubstituted oxazoles from easily available methyl ketones and benzylamines without any metal and peroxide catalyst. This domino oxidative cyclization process involves the cleavage of C H bond and the formation of C-N, C-O bonds. (C) 2012 Elsevier Ltd. All rights reserved.
