摘要: 1H NMR和13C NMR研究了β-环糊精对外消旋布洛芬的手性识别. 外消旋布洛芬与β-环糊精形成包合物后,其1H NMR和13C NMR图谱的化学位移和峰形都有所变化,手性碳附近的某些原子所对应的吸收峰裂分为两组信号, 这两组信号分别对应布洛芬的两种対映异构体. 结果显示, 对于布洛芬, β-环糊精是一个方便而有效的手性溶解剂. 

Abstract: The chiral recognition of racemic ibuprofen by β-cyclodextrin was studied by 1H and 13C NMR spectroscopy. The 1H and 13C spectra of ibuprofen complexing with β-cyclodextrin were shown to be different from those of free ibuprofen. Some peaks of the atoms adjacent to the chiral carbon atom showed splitting into two parts, corresponding to the two enantiomers of ibuprofen respectively. The result demonstrated that β-cyclodextrin can be used as a convenient and effectual chiral solvating agent.

Key words: NMR, β-cyclodextrin, ibuprofen, chrial discrimination, chiral solvating agent
