摘要:

Due to the difference in reactivity of enantiomers with chiral reagents, it was found that in the Fast Atom Bombardment (FAB) mass spectra of enantiomer mixtures of R-α-phenylethylamine and S-α-phenylethylamine with a chiral reagent S-phosphorsaeure-(1,1′-bi-naphthyl-2,2′-diylester) (BNP acid), the relative abundance of the characteristic ion is linearly related to the composition of the mixture. We have, therefore, proposed a possible method for the determination of the optical purity of enantiomers by mass spectrometry.
