The stereochemistries in solution of the diastereoisomeric complexes formed by quinines modified at the hydroxyl site (9-O-acetylquinine; 9-O-(3,5-dimethoxyphenylcarbamate)quinine) or quinuclidine nitrogen (N-benzylquininium chloride) and each enantiomer of 2-(3¢,5¢-dinitrobenzamido)-1-phenylethanol have been compared to those of the free compounds by 1H NMR investigations. Completely different interaction models, also involving changes of the free state conformations, have been obtained.
