Abstract
Optically active 1-(1-naphthyl)ethylamine and 1-hydroxyalkylphosphonic acids form in nonpolar solvents diastereoisomeric salts distinguished in P-31 NMR spectroscopy. The magnetic nonequivalence of phosphonate groups is large enough (esp. for benzyl monoesters salts DELTAdeltaP-3 1 is up to 0.36 ppm) to determine ee values. The dependence of diaster eoisomeric salts magnetic nonequivalence on concentration and enantiop urity of amine component is studied.
