Pyrrolic and imino (3) or amino (4) H-bonding ligands were incorporated into a benzene- based tripodal scaffold to develop a new generation of receptors for molecular recognition of carbohydrates. Receptors 3 and 4 effectively bound a set of octylglycosides of biologically relevant monosaccharides, including glucose (Glc), galactose (Gal), mannose (Man), and N- acetyl-glucosamine (GlcNAc), showing micromolar affinities in CDCl3 and millimolar ...
