摘要：
Michael-type addition of diethyl phosphoramidate to alpha,beta-unsaturated esters occurs when the reactants are refluxed in toluene or xylene with an excess of potassium carbonate in the presence of tetrabutyl-ammonium bromide (TBABr). Dephosphorylation of methyl and ethyl acrylate adducts leads to the respective beta-alanine esters.
