A new synthetic route to macrocyclic sucrose-based receptors with different substituents at the ring nitrogen atom is described. Very good enantioselectivity toward phenylethylammonium chloride was observed [a much stronger complex with the cation of the (S)-amine was formed] although the Ka values were low. Much higher Ka (1.4 × 10 4 M-1 in CDCl3/CD3OD) values of the complexes with aminoacid derivatives (especially valine) were found although this time the enantioselectivities were moderate.
