摘要: 以溴代正丁烷与1-(2,3,4,6-四-O-乙酰基-β-D-吡喃葡萄糖基)咪唑(化合物1)为原料合成了溴化1-(2,3,4,6-四-O-乙酰基-β-D-吡喃葡萄糖基)-3-正丁基咪唑盐(化合物2),它是葡萄糖衍生的手性N-杂环卡宾前体.化合物2的结构中存在多个手性碳原子,导致它的核磁共振(NMR)谱较为复杂.在此,用元素分析、红外吸收光谱(IR)以及液相色谱-高分辨质谱(LC-HRMS)对它的组成进行了分析,然后利用1D和2D NMR谱(包括1H NMR、13C NMR、DEPT135、DEPT90、DEPT45、COSY、1H-13C HSQC、1H-13C HMBC)对化合物21H和13C NMR信号进行了归属.

Abstract: 1-(2,3,4,6-tetra-O-acetyl-β-D-glucopyranosyl)-3-butylimidazolium bromide (compound 2) was synthesized with 1-bromobutane and 1-(2,3,4,6-tetra-O-acetyl-β-D-glucopyranosyl) imidazole (compound 1), which is a glucose-derived chiral N-heterocyclic carbene precursor. Multiple chiral carbon atoms in compound 2 lead to quite complex nuclear magnetic resonance (NMR) spectra. In this study, we analyzed compound 2 using elemental analysis, infrared absorption spectroscopy (IR), liquid chromatography-high resolution mass spectrometry (LC-HRMS), and assigned the 1H NMR and 13C NMR signals with one-dimensional (1D) and two-dimensional (2D) NMR spectroscopy, including 1H NMR, 13C NMR, DEPT135, DEPT90, DEPT45, COSY, 1H-13C HSQC and 1H-13C HMBC.

Key words: liquid NMR, chiral N-heterocyclic carbene precursor, glucose, spectral analysis
