摘　　要：The title compound 2 was synthesized by the reaction of 3-keto-D-xylose with O-C6H4NH2NH2 and characterized by IR, NMR and HRMS, and its crystal structure was determined by X-ray diffraction analysis. The crystal is of orthorhombic system （C21H22N2O5, Mr = 382.41）, space group P2 1 2 1 2 1 with α = 10.140（2）, b = 10.802（2）, c = 17.840（4） A, β = 90°, V = 1954.1（7）A^3, Z = 4, Dc = 1.300 g/cm^3, F（000） = 808, μ = 0.094 mm^-1, the final R = 0.0354 and wR = 0.0514 for 1924 observed reflections （I 〉 2σ（I））. One intermolecular and one intramolecular hydrogen bonds were found. The absolute configuration of this molecule was confirmed by comparison with that of the original material.The title compound 2 was synthesized by the reaction of 3-keto-D-xylose with O-C6H4NH2NH2 and characterized by IR, NMR and HRMS, and its crystal structure was determined by X-ray diffraction analysis.
