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。
