An improved method for the synthesis of pentafluoroethylated pyridines through Cu-catalyzed[3+3] cyclo-addition reaction of oxime acetates is reported. The starting materials are more readily available, and these reactions occurred under mild conditions with broad substrate scope and excellent regioselectivity. Mechanistic studies have also been preformed.
Key words: pentafluoroethylated, pyridines, copper-catalyzed, oxime acetates
