New enantiomerically pure dimethyl-substituted pyridino-18-crown-6 ether derivatives containing chloro, N-allylamino, N-allylacetamido, N-benzylamino and cyano functional groups at position 4 of the pyridine ring have been synthetized. This paper also reports the transformation of the known enantiopure parent dimethyl-substituted pyridino-18-crown-6 ether to its new N-oxide derivative and the O-methylation of the latter. These ligands are good candidates for enantiomeric recognition studies of protonated primary amines, amino acids and their derivatives.
