摘要

A copper-catalyzed 1,2-diol amination at the electron-rich C-5 position of unprotected 2-amino/2hydroxy-5-halopyridine provided excellent yields. Selective amination preferably at C-5 in 2-bromo-5-iodopyridine was achieved under the same conditions. The selective, generally mild and economical coupling reaction at C-5 position described herein could be achieved with amines, heterocycles and amides.
