摘要
A mild and efficient method for etherification of cyclic beta-diketones with alcohols has been developed Using a catalytic amount of cerium(IV) ammonium nitrate at room temperature to afford the corresponding beta-keto enol ethers in good to excellent yields. The deprotections of enol ethers in water-acetonitrile (1:1) using a catalytic amount (10 mol %) of cerium(IV) ammonium nitrate have also been achieved.
