Abstract Treatment ofN-bromosuccinimide NBS with carboethoxymethylene triphenylphosphorane 1 in CH2Cl2 followed by the addition of an alcohol in the presence of manganese dioxide under ultrasonic irradiation constitutes a stereoselective one-pot procedure for the preparation of Z-configured α–bromo-α,β-unsaturated esters in good to excellent yield.

Keywords: one-pot synthesis; bromoylides; oxidation; α–bromo-α,β-unsaturated esters one-pot synthesis; bromoylides; oxidation; α–bromo-α,β-unsaturated esters
