Abstract

A copper-catalyzed oxidative coupling of 2-carbonyl-substituted phenols and 1, 3-dicarbonyl compounds with a wide range of dibenzyl or dialkyl ethers is described. This protocol provides an efficient preparation of phenol esters and enol esters in good yields with high chemoselectivity. This method represents an alternative protocol for classical esterification reactions.
