GRAPHICAL ABSTRACT

ABSTRACT

Precolumn chiral derivatization of fluorinated aminophosphonic acids was successfully accomplished with standard reagent consisting of N-acetyl-L-cysteine and o-phthaldialdehyde. Thus formed diastereomeric isoindole derivatives were characterized by means of ultraviolet- and mass-spectroscopic techniques. The chromatographic behavior of diastereomeric isoindole derivatives has been studied on different reverse phase columns. Operationally simple chromatographic analysis enabled the selective discrimination of fluorinated aminophosphonic acid enantiomers.
