Abstract: Benzoxazoles are synthesised directly by oxidative condensation of primary and secondary amines with o-aminophenols under hydrogen transfer catalysis. The optimal system utilises 1mol% of the Shvo catalyst, with dimethoxybenzoquinone as the hydrogen-accepting terminal oxidant. [Copyright &y& Elsevier]
