摘　　要：The crystal structure of the title compound, diethyl 5-acetoxy-3-（4-chlorophenyl）-4,5- dihydroisoxazol-5-yl-5-phosphonate （C15H19CINO6P, Mr = 375.73）, has been synthesized by the treatment of nitrile oxides and l-acetyloxy-vinylphosphonate under very mild conditions in good yields, and determined by single-crystal X-ray diffraction. The crystal belongs to monoclinic, space group C2/c with a = 16.914（10）, b = 10.567（7）, c = 21.927（13） A, β = 110.249（11）°, V = 3677（4） A^3, Z = 8, Dc = 1.358 g/cm^3, F（000） = 1568,/l（MoKa） = 0.324 mm^-1）, S = 1.011, the final R = 0.0661 and wR = 0.1556. The X-ray analytic results showed that the dihedral angle between the phenyl group and the isoxazoline ring is 10.7°.The crystal structure of the title compound, diethyl 5-acetoxy-3-（4-chlorophenyl）-4,5- dihydroisoxazol-5-yl-5-phosphonate （C15H19CINO6P, Mr = 375.73）, has been synthesized by the treatment of nitrile oxides and l-acetyloxy-vinylphosphonate under very mild conditions in good yields, and determined by single-crystal X-ray diffraction.
