New chiral stationary phases (CSPs) based on chiral selectors covalently bound on a solid support were prepared. Chiral selectors were obtained from enantiomerically pure aromatic amines and 3,5-dinitrobenzoic acid and then linked to the support surface through the allylic double bond. Such obtained materials allow enantioseparation of racemates or enantiomerically enriched compounds. These chiral stationary phases can be used as fillings in chromatographic columns for enantiomer separation of naproxen type drugs and other similar non-steroidal anti-inflammatory drugs (NSAID) by means of high performance liquid chromatography on both the analytical and preparative scale.
制备了基于手性选择剂共价结合在固体支撑上的新手性固定相(CSPs)。手性选择剂是从对映异构体纯的芳香胺和3,5-二硝基苯甲酸中获得的,然后通过烯丙基双键连接到支撑表面上。这种材料可以对混合物或对映体富集化合物进行对映异构体分离。这些手性固定相可以作为填充物用于色谱柱,通过高效液相色谱在分析和制备尺度上对萘普生类药物和其他类似的非甾体抗炎药(NSAID)进行对映异构体分离。
