Ethyl α-mercaptoacetate and ethyl α-mercaptopropionate dianions were found to be useful reagents for the synthesis of α,β-unsaturated esters from carbonyl compounds by a single operation under mild conditions. Highly substituted α,β-unsaturated esters could be prepared by this method. The application to the synthesis of a component of ant mandibular gland secretions was described.
