A simple and efficient trans-acetoacylation method for the synthesis of beta-keto ester derivatives has been described using ytterbium(III) triflate as a new catalyst under solvent-free condition. This method was found to be efficient and convenient for the synthesis of a wide variety of beta-keto ester derivatives. (C) 2011 Elsevier Ltd. All rights reserved.
