alkaloid-based chiral stationary phase preparation is described. Synthesis is based on bonding the allyl derivative of terguride to mercaptopropylsilanized silica gel. The packing exhibits higher content of chiral selector, stability, reproducibility, and enantioselectivity toward amino acids compared to that previously studied. The chromatographic behavior of amino acids with different side chains and substituent
描述了一种基于麦角生物碱的手性固定相制备的新方法。合成是基于将特固脲的烯丙基衍生物与巯基丙基硅烷化的硅胶结合。与先前研究的相比,该填料表现出更高的手性选择剂含量,稳定性,可再现性和对氨基酸的对映选择性。研究了具有不同侧链和取代基的氨基酸的色谱行为,以便更深入地了解对映鉴别机理,并确定特固利作为此类化合物的手性选择剂的局限性和强度。检查了多种因素,包括流动相参数,例如pH,离子强度,有机改性剂的含量和性质以及温度。
