Synthetic Hydrogen-Bonding Receptors for Biologically Essential Monosaccharides

抄録

Novel macrocyclic saccharide receptors that possess terpyridine skeletons as a hydrogen-bonding site are presented. On modification of the hydrogen-bonding sites and the macrocyclic bridges, the receptors showed selective bindings for ribofuranosides, deoxyribofuranosides, and glucopyranosides, respectively. The binding affinities of the receptors were very high, so that native monosaccharides were solubilized into non-polar solvents in the presence of the receptors. The hydrogen-bonding interactions and the binding modes between them were characterized by ¹H NMR spectroscopy.
