Abstract
An efficient Cu-catalyzed annulation reaction of ketone oxime acetates with ortho-trifluoroacetyl anilines has been disclosed. With the developed protocol, a series of 4-trifluoromethyl quinolines were obtained in good to excellent yields (58-99%) under redox-neutral conditions. The protocol also could be extended to ferrocene-based ketone oxime acetates for the construction of ferrocene-substituted fluorine-containing quinolines.
