ملخص: New [alpha]-hetero [beta]-enamino esters 5 (X = NH, O, S) are obtained in good to excellent yields by transamination reactions from ethyl 3-dimethylamino acrylate 2(a-c) and various volatile amines 3(a-e) using solvent-free conditions assisted by focused microwave irradiation. Most of the [alpha]-hetero [beta]-enamino ester derivatives 3 present a (E)-s-cis/trans conformation.
