Abstract
Ion trap mass spectrometry (ITMS) was employed to study chiral guest-exchange reactions in gas-phase complexes of amino acids and β-cyclodextrin. Enantioselectivity was obtained with a selected group of amino acids containing alkyl side chains. The selectivity for the amino acids increased with the size of the side chain except for Phe where the selectivity dropped off considerably. The results were consistent with those obtained earlier with Fourier-transform mass spectrometry (FTMS). The two mass analyzers were compared with regard to enantiomeric analysis.
