PIFA-Mediated Ring-Opening/Coupling Reaction of Benzoxazoles: Access to 2-Hydroxy Diarylureas
A efficient method for synthesizing asymmetric 2-hydroxy diaryl ureas has been developed via phenyliodine bis(trifluoroacetate) (PIFA)-mediated ring-opening/coupling of benzoxazoles with aryl isocyanates or isothiocyanates. This transition-metal-free protocol operates under mild conditions and utili...
