摘　　要：以1-(2,6-二甲基苯基)-1H-咪唑与2-溴乙基葡萄糖苷为原料,一步合成了新化合物溴化1-(2,6-二甲基苯基)-3-[2-(2,3,4,6-四-O-乙酰基-β-D-吡喃葡萄糖基氧基)-乙基]-咪唑盐(化合物1),是一种咪唑啉盐表面活性剂。化合物1的结构中存在糖基,含有多个手性碳原子,导致其核磁共振氢谱和碳谱较为复杂。我们运用液相色谱-高分辨质谱(LC-HRMS)和元素分析(EA)确定了其化学组成,随后通过液体核磁共振波谱技术(包括1D和2D核磁共振手段,如1H NMR、13C NMR、DEPT90、DEPT135、1H-1H COSY、1H-13C HSQC、1H-13C HMBC)对化合物1的氢谱和碳谱信号进行了表征,通过解析对其结构进行了详尽归属。1-(2,6-dimethylphenyl)-3-[2-(2,3,4,6-tetra-O-acetyl-β-D-glucopyranosyloxy)-ethyl]-imidazolinium salt(Compound 1)is synthesized by 1-(2,6-dimethylphenyl)-1H-imidazole and 2-bromoethylglucoside,which is a glucose-derived chiral imidazolinium surfactants.The structure of compound 1 has sugar groups and multiple chiral carbon atoms,which makes its 1H nd 13C NMR spectrum more complicated.Herein,we used liquid chromatography-high resolution mass spectrometry(LC-HRMS)and elemental analysis(EA)to determine its chemical composition,and subsequently characterized the hydrogen and carbon spectrum signals of compound 1 by liquid NMR spectroscopy(including 1H,13C,DEPT90,DEPT135,1H-1H COSY,1H-13C HSQC and 1H-13C HMBC),finally,the 1H and 13C NMR chemical shift was completely assigned.
