The solid phase synthesis of a guanidinium based 'tweezer' receptor

Article abstract of DOI:10.1016/0040-4039(96)01058-1

An appropriately functionalised guanidine has been connected to a solid support, allowing peptide chains to be attached by conventional solid phase synthesis. This provides the basis for the solid-phase synthesis of libraries of 'tweezer' receptors for peptides with a carboxylate terminus.
