Abstract

A practical and efficient method for the construction of poly substituted oxazoles has been developed using a catalytic amount of potassium iodide and TBHP as the green oxidant via amidation followed by intramolecular oxidative cyclization of enaminone derivatives under mild reaction conditions. The attracting feature is oxidation of benzylic C–H bond and dehydrogenation of enaminone occurred in one pot under base free conditions. [Display omitted] [ABSTRACT FROM AUTHOR]
