A novel strategy for direct aryl hydroxylation via Pd-catalysed Csp2-H activation through an unprecedented hydroxyl radical transfer from 1,4-dioxane, used as a solvent, is reported with bio relevant and sterically hindered heterocycles and various acyclic functionalities as versatile directing groups.

A novel, one-pot, phenylboronic acid catalyzed, cyanide promoted synthesis of 2-(2-hydroxyphenyl)benzoxazoles from salicylaldehydes and o-aminophenols is described. The synthesis is characterized by mild conditions, short reaction times, and simple workup of crystalline, high purity products.

A general synthetic method for benzoxazoles, benzimidazoles and benzthiazole is described.Treatment of the imidoyl chloride of 1,3-benzoxazine with 2-aminophenols gave the corresponding 2-hydroxyphenylbenzoxazoles in good yields.Similarly, 2-hydroxyphenylbenzimidazoles and 2-hydroxyphenylbenzthiazole were obtained using o-phenylenediamines and 2-aminothiophenol, respectively.
