Abstract
Compositions and methods of incorporating ligand precursors and ligands at any location within a peptide during peptide synthesis are disclosed. Derivatives of 2,4,5-triaminopentanoic acid and .gamma.-aminoglutamic acid are selectively incorporated into the peptide during solid phase or liquid phase synthesis, depending upon the choice of protecting groups. Ligand synthesis may then be completed at a later time to produce N.sub.3 S, N.sub.2 S.sub.2, and EDTA type chelating agents.
