Enantiodifferentiation of α-Arylacetic Acid and Thiohydantoin Derivatives by NMR Using Thiourea-Based Chiral Solvating Agents

Molecules
Two thiourea-based chiral solvating agents (CSAs), S-1 and S-2, were evaluated for the enantiomeric discrimination of representative α-arylacetic acids by 1H NMR spectroscopy in the presence of DMAP. Enantiomeric discrimination was assessed by monitoring
