Abstract We report a two-step rapid and efficient synthesis of β-amino-α,β-unsaturated esters. Microwave-assisted synthesis was used throughout the process. Seventeen β-amino-α,β-unsaturated esters were produced in excellent yields and short reaction times. The effects of the heating method and substituents, especially the o-substituted group of the phenols or thiophenols, were investigated. A plausible
