Highly lipophilic enantiomerically pure pyridino- and pyridono-18-crown-6 type ligands containing four stereogenic centers to which butyl or butoxymethyl groups are attached have been synthesized. X-Ray analysis of the (R)-1-phenylethylammonium and benzylammonium perchlorate complexes of the unsubstituted pyridono ligand revealed, that, in contrast to the free ligand, in the complex the hydroxypyridine tautomer is present.
