Cu-catalyzed intramolecular hydroarylation of alkynes†
Abstract
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, heteroaryl, alkyl, and even N-group attached alkynes are all suitable substrates for the intramolecular hydroarylation.
