A Supramolecular Extension of Mosher’s Method: Absolute Configuration Assignment of <i>N</i>-Amino Acid Derivatives via Bis-Thiourea Chiral Solvating Agent

A Supramolecular Extension of Mosher’s Method: Absolute Configuration Assignment of <i>N</i>-Amino Acid Derivatives via Bis-Thiourea Chiral Solvating Agent

The bis-thiourea chiral solvating agent (CSA) <b>BTDA</b> enables the NMR-based determination of absolute configuration in <i>N</i>-3,5-dinitrobenzoyl (DNB) amino acid derivatives without requiring covalent derivatization. A reliable trend of the sense of nonequivalence and a...
