An efficient Cu(II)-vasicine catalytic system has been developed for intramolecular CN bond formation. In this way, regioselective 2-amination of o-haloanilides with aqueous ammonia in EtOH has been achieved. This strategy provides several advantages, such as good regioselectivity, high yields and functional group tolerance.

Using CuI/xantphos/Pd(OAc)(2) catalytic system, the intermolecular C-C cross coupling between benzoxazoles and ortho-haloanilides has been developed in moderate to good yields. The procedure tolerates a series of functional groups on benzoxazole, such as ester, chloro, methyl, and methoxy groups. This divergent approach provides access to various N-(2-Benzoxazol-2-ylphenyl)amides. (C) 2015 Elsevier Ltd. All rights reserved.
