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.

A simple and efficient transesterification process for the synthesis of β-ketoester derivatives has been achieved by the reaction of methyl β-ketoester with higher alcohols at 110 °C undersolvent-free, catalyst-freeconditions and its application in synthesis of 3,4-dihydropyrimidin-2(1H)-ones C-5 ester derivatives via Biginelli reaction has been described.
