We report herein results on the enantioseparation of selected racemic amine and amino ester hydrogen perchlorate salts using a silica gel-bound optically pure chiral di-tert-butylpyridino-18-crown-6 ligand (R,R)-1. The effect of solvent composition w

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

Dithionoamide ligand 8 exhibited a time-dependent optical rotation. The first measurement was taken after two minutes of dissolution of the crystals (recrystallized from ethanol). The optical rotation of this solution increased gradually and after 30
