Different kinds of amino acids, directly serving as nucleophiles, were reacted with (5S)-5-alkoxy-3,4-dihalo-5H-furan-2-ones via tandem asymmetric Michael addi-tion-elimination in the presence of potassium hydroxide to give 15 new optically active 5H-furan-2-one derivatives. The chemical structures and absolute configurations of these compounds were confirmed via rotation, UV-Vis, IR, 1H NMR, 13C NMR, MS, elemental analysis and X-ray single crystal diffraction.

Key words: (5S)-5-alkoxy-3,4-dihalo-5H-furan-2-one, amino acid, tandem Michael addi-tion-elimination, optical activity, multiple chiral center
