A series of regioselectively isoxazolines were synthesized through cycloaddition reaction of nitrile oxides with vinylphosphonate. The structure of title compound was proved as 5-phosphonyl isoxazoline by X-ray crystallography of compound 3c. Their structures were confirmed by NMR, ESI-MS and elemental analysis. We have tested suppression of the NIs, and found they can inhibit neuraminidase.

Key words: Vinylphosphonates, nitrile oxides, 1,3-Dipolar cycloadditions, isoxazoline
