No separation is needed! The enantiomeric excess of unprotected amino acids can be determined very reliable by P-31 NMR spectroscopy after derivatization as phosphonic amides 1. This rapid and simple analytical procedure, suitable for aqueous solutions. is also applicable for amino acid derivatives, chiral amines, and alcohols.</p
