A series of thiourea and guanidinium derivatives have been prepared and their ability to bind a carboxylate group has been investigated. Guanidinium 33, featuring two additional amides and a pyridine moiety, proved to be the most potent carboxylate binding site and was able to bind acetate in aqueous solvent systems (Kass= 480 M− 1 in 30% H2O–DMSO). The pyridine moiety is critical to obtaining strong binding, and comparison with the binding ...
