Palladium-catalyzed direct arylation of benzoxazoles with unactivated simple arenes

Abstract

Using CuBr(2) as an additive, the Pd-catalyzed intermolecular C-H-C-H cross-coupling between benzoxazoles and unactivated simple arenes has been developed. This protocol provides a straightforward approach for the biological activity of 2-arylbenzoxazole derivatives.
