3,5-DINITROBENZOYL AMINO ACID ESTERS. BROADLY APPLICABLE CHIRAL SOLVATING AGENTS FOR NMR DETERMINATION OF ENANTIOMERIC PURITY.

Article abstract of DOI:10.1016/S0040-4039(00)98599-X

Methyl esters of N-(3,5-dinitrobenzoyl)-amino acids have been used as chiral solvating agents to induce NMR spectral nonequivalence between the enantiomers of a broad array of solutes.
