The separation of enantiomers by chromatographic methods, such as gas chromatography, high-performance liquid chromatography and capillary electrochromatography, has become an increasingly significant challenge over the past few decades due to the demand of pharmaceutical, agrochemical, and food analysis. Among these chromatographic resolution methods, high-performance liquid chromatography based on chiral stationary phases has become the most popular and effective method used for the analytical and preparative separation of optically active compounds. This review mainly focuses on the recent development trends for novel chiral stationary phases based on chitosan derivatives, cyclofructan derivatives, and chiral porous materials that include metal-organic frameworks and covalent organic frameworks in high-performance liquid chromatography. The enantioseparation performance and chiral recognition mechanisms of these newly developed chiral selectors toward enantiomers are discussed in detail.
过去几十年来,由于药物、农化和食品分析的需求,通过色谱方法(如气相色谱、高效液相色谱和毛细管电色谱)分离对映异构体已成为一项日益重要的挑战。在这些色谱拆分方法中,基于手性固定相的高效液相色谱已成为分析和制备分离光学活性化合物最受欢迎和有效的方法。本综述主要关注基于壳聚糖衍生物、环糊精衍生物以及手性多孔材料(包括金属有机骨架和共价有机骨架)的新型手性固定相在高效液相色谱中的最新发展趋势。详细讨论了这些新开发的手性选择器对映异构体的对映体的手性拆分性能和手性识别机制。
