摘要: 合成了苯基氨基甲酸酯衍生化β-环糊精键合固定相CSP1和CSP2,在正相色谱条件下,一系列α-氨基膦酸酯化合物首次在这类衍生化β-环糊精固定相上实现了手性拆分.探索运用定量结构-对映异构体选择性保留关系的方法,将对映异构体的色谱保留和溶质分子描述参数进行相关性联系建立定量方程,对比研究了该类苯基氨基甲酸酯衍生化β-环糊精键合固定相上可能的液相色谱保留和手性识别机理

Abstract: The phenyl carbamate derivative β-cyclodextrin bonded phase CSP1 and CSP2 were prepared by the reaction of phenyl isocyanate. In normal phase condition, the enantiomers of a series of α-aminophosphonates have been separated on CSP1 and CSP2 by HPLC. In order to compare the different chromatographic property between the two CSPs, four molecular describing parameters reflecting the properties of the solutes were chosen to correlate against the experimental logarithim value of the capacity factor to form the quantitative structure enantioselective retention relationships(QSERRs) by the multivariable regression analysis and the factor analysis method. Through the QSERRs, the retention and enantioselectivity mechanism were examined.

Key words: HPLC, Cyclodextrin bonded phase, &alpha, Aminophosphonate, Chiral recognition mechanism, Quantitative structure enantioselective retention relationship
