the separation efficiency and elution order of enantiomeric α‐hydroxyallyl phosphonates and their carbonate derivatives on commercially available polysaccharide AS, ad, OD, IC‐3, and Whelk‐O 1 CSPs. In general, the α‐hydroxyallyl phosphonates were resolved on the AS‐H CSP, whereas the carbonate derivatives 1b and 2b were preferentially resolved on the ad‐H CSP. The impact of aryl substitution on the
使用Chiralpak AS‐H和ad ‐H手性固定相(CSP)的高效液相色谱(HPLC)证明了母体化合物α-羟基烯丙基二甲基膦酸二甲酯1a和1-(二甲氧基磷酰基)烯丙基碳酸1b的对映体的色谱分离分别使用紫外线,偏振和折射率检测器的组合。在市售多糖AS,ad,OD,IC-3和Whelk-O 1 CSP上,对映体α-羟基烯丙基膦酸酯及其碳酸盐衍生物的分离效率和洗脱顺序进行了比较。通常,α-羟基烯丙基膦酸酯是在AS-H CSP上拆分的,而碳酸盐衍生物1b和优先在ad ‐ H CSP上解决了2b。芳基取代的对分析物的分辨率的影响1d中,1E,1F和2,3,4,5,6,7,8进行评价。测定AS-H CSP上对映选择性吸附的羟基膦酸酯1a和4以及ad -H CSP上的碳酸酯1b的热力学参数证明了对映体分离的焓控制。手性28:656–662,2016。©2016 Wiley Periodicals,Inc
