Six chiralderivatives of xanthones (CDXs) were covalently bonded to silica, yielding the corresponding xanthonic chiralstationaryphases (XCSPs). The new XCSPs were packed into stainless‐steel columns with 150 x 4.6 mm i.d. Moreover, the greening of the chromatographic analysis by reducing the internal diameter (150 x 2.1 mm i.d.) of the liquid chromatography (LC) columns was also investigated. The
氧杂蒽酮(CDXs)的六个手性衍生物共价键合到硅胶上,产生相应的黄原酮手性固定相(XCSPs)。将新的XCSP装入内径为150 x 4.6 mm的不锈钢色谱柱中。此外,还研究了通过减小液相色谱(LC)色谱柱的内径(150 x 2.1 mm id)进行色谱分析的绿色方法。使用不同化学类别的手性化合物,包括几种药物,通过LC评估了这些相的对映选择性。为了探索对等原则以及手性自我识别现象,对CDXs库进行了评估。在多峰洗脱条件下研究了CDXs对映体混合物的分离。XCSP对主要在正相洗脱条件下评估的CDX对映体混合物提供了高特异性。此外,用相同的黄药选择剂的两种对映体制备了两种XCSP,以确认其反相顺序洗脱。

the development of new chiralstationaryphases (CSPs) for liquidchromatography (LC) based on chiral derivatives of xanthones (CDXs). Based on the most promising CDX selectors, 12 new CSPs were successfully prepared starting from suitable functionalized small molecules including xanthone and benzophenone derivatives. The chiral selectors comprising one, two, three, or four chiral moieties were covalently
最近,我们报道了基于氧杂蒽酮(CDXs)的手性衍生物的液相色谱(LC)的新手性固定相(CSP)的开发。基于最有前途的CDX选择器,成功地从合适的功能化小分子(包括one吨酮和二苯甲酮衍生物)制备了12种新的CSP。将包含一个,两个,三个或四个手性部分的手性选择剂共价键合到色谱载体上,并进一步填充到LC不锈钢柱(150×2.1 mm ID)中。使用不同种类的手性化合物通过LC评估了新CSP的对映选择性。在评估新的CSP时观察到了对映体分离某些CDX的特异性。除了,通过使用分子对接方法的计算研究对手性识别机理进行了评估,这与色谱参数相符。X射线分析用于建立手性选择器3D结构。
