Synthesis and evaluation of an enterobactin model compound. 1,3,5-Tris-(2,3-dihydroxybenzoylaminomethyl)benzene and its iron(III) complex

Abstract
The title compound, an analogue of the siderophore enterobactin, acts as a hexadentate ligand for FeIII ion, co-ordinating via the six phenolic oxygens to give a complex whose overall formation constant is 1045.8.
