An N-hydroxyl peptide unit of H-L-Pro-L-Ala-L-Ala-β-(BnO)Ala-OMe was synthesized by stepwise chain building method in solution. Then, based on nitrilotriacetic acid backbone and this N-hydroxyl peptide unit, a novel chiral tripodal ligand P as an analogue of desferrichrome, has been synthesized. In neutral pH, ligand P formed stable tri(hydroxamato)-iron(Ⅲ) complexes which showed a maximum absorption (Emax=2750 M-1cm-1) at 422 nm in UV-Vis spectra. The characteristic absorption spectra are similar to those of natural trihydroxamate-type siderophores.
