Triscarboxylic acids, when treated with hydroxylamines in the presence of water-soluble carbodiimide in THF-H2O, at pH≈4.8, yield the corresponding trishydroxamic acids in good yields.
We describe a synthetic route involving phase
transfer catalysis leading to a series of tripodal
N-alkylated hydroxamic acids as models of
desferrioxamine; iron(III) exchange reactions between
their iron complexes and EDTA were investigated.
