acid and its analogs have been chromatographically separated on a chiral stationary phase (CSP) derived from 4‐(3,5‐dinitrobenzamido) tetrahydrophenanthrene. The rationale of separations of these compounds is discussed with respect to the method development for determining enantiomeric purity and possibility of obtaining enantiomerically pure materials by high‐pressure liquid chromatography. The relationship
扁桃酸及其类似物的对映异构体已在手性固定相(CSP)上进行色谱分离,手性固定相衍生自4-(3,5-二硝基苯甲酰胺基)四氢菲。关于确定对映体纯度的方法发展以及通过高压液相色谱法获得对映体纯物质的可能性,讨论了分离这些化合物的原理。已经检查了分析物结构与对映异构体分离程度的关系,并给出了各组结构相关化合物的分离因子(α)。已经提出手性识别模型可以解释观察到的分离。这些模型为手性识别过程提供了机械的见解。手性2010。©2009 Wiley‐Liss,Inc.。
