The terpenoid chiral selectors dehydroabietic acid, 12,14-dinitrodehydroabietic acid and friedelin have been covalently linked to silica gel yielding three chiral stationary phases CSP 1, CSP 2 and CSP 3, respectively. The enantiodiscriminating capability of each one of these phases was evaluated by HPLC with four families of chiral aromatic compounds composed of alcohols, amines, phenylalanine and
萜类手性选择剂脱氢松香酸,12,14-二硝基脱氢松香酸和弗瑞德林已与硅胶共价连接,分别得到三个手性固定相CSP 1,CSP 2和CSP 3。通过HPLC,用由醇,胺,苯丙氨酸和色氨酸氨基酸衍生物和β-内酰胺组成的四族手性芳族化合物评估了这些相中每一相的对映异构能力。该CSP 3相,含有具有大木栓骨架的选择是特别适合于解决游离醇以及它们的衍生物轴承氟取代基,而CSP 2具有脱氢松香结构的化合物是唯一可有效区分1,1'-联萘酚阻转异构体的相。CSP 3还可以有效拆分游离胺。所有三个相都很好地分解了N-三氟乙酰基和N -3,5-二硝基苯甲酰基苯基丙氨酸氨基酸酯衍生物的外消旋物。在CSP 1上实现了良好的对映体β-内酰胺和N-苯甲酰色氨酸氨基酸衍生物的分离。
