The azamacrocyclic complex was used as a platform for the construction of [3]rotaxanes containing two DB24C8 macrocycles per molecule. The complex unit incorporates two electron deficient π-bond systems and two N-H hydrogen bond donating groups which faci

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.
