Abstract
AbstractA bisimidazoline compound has been prepared as a new chiral solvating agent starting from isophthalaldehyde and (S,S)‐1,2‐diphenylethylenediamine through a single‐step synthesis. In the presence of one equivalent of this reagent, carboxylic acid racemates show 1H NMR chemical shift nonequivalences large enough for the discrimination of the enantiomers. Studies with related compounds showed that the 1,3‐disubstituted structure is crucial for the acid‐solvating ability of the bisimidazoline compound.
