Novel macrocyclic compounds, synthesized and used as chiral solvating agents for phosphinic, phosphonic, and phosphoric acids, are reported in this article. NMR (1H NMR and/or 31P NMR) studies demonstrate that these acids have large nonequivalent chemical shifts in the presence of these macrocyclic compounds. Quantitative analyses of a series of the selected phosphinic acids with different enantiomeric purities show the high accuracy of this method.
