Cu-catalyzed intramolecular hydroarylation of alkynes

An efficient Cu-catalyzed intramolecular hydroarylation reaction of alkynes has been developed. The reaction is accomplished under mild conditions and shows good tolerance to both electron-rich and electron-deficient aryl nucleophiles. A series of aryl, h
