合成了β-Ｄ-O四乙酰基糖基叠氮化合物， 并得到单晶， 经X射线衍射方法解析， 其晶系属于单斜晶系，P2₁空间群， 其中a=0.759　6(6) nm,b=1.518　4(13) nm，c=1.641　2(14) nm，V=1.893　0(3) nm³，α=90.00°，β=90.045(1)°，γ=90.00°，Z=2. 在晶体结构中， 六元糖环采取经典⁴C₁椅式构象， 糖环上所有的取代基均以平伏键存在， 其中叠氮基不是以直线型结构存在， 呈现一定的弯曲现象.

Synthesis and Crystal Structure of β-D-O-Acetyl-glycopyranosyl Azide

Compound 2,3,4,6-tetra-O-acetyl-β-Ｄ-glycopyranosyl azide was synthesized and characterized by means of single crystal X-ray diffraction. It crystallized in the monoclinic space group P2₁with crystallographic parameters a=0.759　6(6) nm, b=1.518　4(13) nm, c=1.641　2(14) nm, α=90.00°, β=90.045(1) °, γ=90.00°, Z=2, V=1.893　0 (3)nm³. In the crystal structure of the title compound, the hexopyranosyl ring adopt a normal ⁴C₁ chair conformation and all the substituents occupy equatorial position and the azide group do not adopt beeline structure but has curve phenomena.
