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
