摘要：

beta-Keto enol ethers have been synthesized in very good yield in solvent-free conditions from differently substituted alcohols and beta-diketones in the presence of Yb(OTf)(3) as catalyst. The method is applicable to both cyclic and acyclic beta-diketones with only slight differences in the experimental procedure. (c) 2006 Elsevier Ltd. All rights reserved.
