Using cyclic secondary amines as nucleophilic reagents, the tandem Michael addition-elimination of 5-alkoxy-3,4-dihalo-5H-furan-2-one in the presence of potassium fluoride gave 17 novel compounds. The chemical structures and absolute configurations of the new compounds were confirmed via rotation, UV-Vis, IR, 1H NMR, 13C NMR, MS, elemental analysis and X-ray single crystal diffraction.

Key words: 5-alkoxy-3,4-dihalo-5H-furan-2-one, cyclic secondary amine, Michael addition, tandem reac-tion, 5-alkoxy-4-cycloamino-3-halo-5H-furan-2-one, synthesis
