The ultrasound assisted facile, rapid and one-pot synthesis of 2-aryl substituted 4,5-diphenyloxazoles was achieved via the reaction of commercially available benzoin (or 2-hydroxy-2-phenylacetophenone) with benzylamines in the presence of IBX under mild conditions. The methodology involved initial IBX mediated conversion of benzoin to benzil and then reaction with benzylamine followed by intramolecular
