title: Copper-catalyzed regio- and stereoselective O-arylation of enolates.
abstract: Copper-catalyzed O-arylation of enolates with diaryliodonium salts as arylating reagents was realized successfully. As important building blocks, β-aryloxy carbonyl compounds were obtained in up to 98% yield under mild conditions, and complete control of O-arylation and Z-stereoselectivity were achieved. The origin of the selectivity was also discussed.
