Copper-Catalyzed One-Pot Trifluoromethylation/Aryl Migration/Desulfonylation and C(sp(2))-N Bond Formation of Conjugated Tosyl Amides
A novel copper-catalyzed one-pot trifluoromethylation/aryl migration/desulfonylation and C(sp(2))-N bond formation with conjugated tosyl amides as starting materials is presented here. The reaction affords alpha-aryl-beta-trifluoromethyl amides bearing a quaternary stereocenter or trifluoromethylated oxindoles in a regioselective manner.
