Pagination or Media Count:
New chiral pyridino-18-crown-6 ligands containing two amide, thionoamide or amine units and two benzyl or phenyl substituents on chiral macroring positions have been synthesized see Figure 1. Some of these chiral ligands exhibit only moderate or no recognition for the enantiomers of alpha- 1-naphthylethylammonium perchlorate as determined by 1H NMR spectral techniques.
