摘要:
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.
