Enantiomer assays of amino acid derivatives using tertiary amine appended trans-4-hydroxyproline derivatives as chiral selectors in the gas phase

A pair of pseudo-enantiomers, tertiary amine appended trans-4-hydroxyproline derivatives were designed, synthesized, and evaluated as chiral selectors for enantiomer analysis of DNB-amino acid and their amides, in single-stage electrospray ionization/mass spectrometric experiments. The chiral select...
