Palladium-catalyzed C-2 selective arylation of quinolines.

An efficient method for the Pd-catalyzed regioselective C-2 arylation of quinolines is presented. Reactions of various substituted quinolines and unactivated arenes have been conducted under mild conditions. The result shows good product yields of 2-arylquinolines, which are highly useful building blocks for the synthesis of bioactive alkaloid natural products and drug molecules.
