Using amino acid esters as nucleophilic reagents, the tandem Michael addition-elimination reaction of 5-alkoxy-3,4-dihalo-5H-furan-2-one in the presence of triethylamine gave 17 novel compounds. The chemical structures and absolute configurations of the new compounds were confirmed via rotation, UV-Vis, IR, H NMR, C NMR, MS, elemental analysis and X-ray single crystal diffraction.

Key words: 5-alkoxy-3,4-dihalo-5H-furan-2-one, amino acid ester, Michael addition, tandem reaction
