Polyhydroxamate desferrioxamines (DFO) are nontoxic siderophores endowed with high potential for development of therapeutic chelating agents. Herein, we report a modular and convergent strategy for diverse synthesis of macrocyclic and linear DFOs. The strategy employed orthogonally protected N-hydroxy-N-succinylcadaverine building blocks, which allowed bidirectional extension of the DFO structure. The efficiency of the new strategy was demonstrated by the total synthesis of 44-membered macrocyclic DFO-T1, as well as four related DFO compounds in 11–13 linear steps and 2.1 %–10 % overall yields. Comparison of the iron binding affinity of the DFOs revealed DFO-E as the best chelator.

The total syntheses of the microbial iron chelator desferrioxamine B hydrochloride and some analogues are described.The syntheric scheme is highly flexible, providing access to dihydroxamate, trihydroxamate, tetrahydroxamate, and higher homologues of desferrioxamines.The procedure also allows for access to primary amino nitrogen functionalized desferrioxamine.The scheme is predicated on the generation of the key intermediate O-benzyl-N-(4-cyanobutyl)hydroxylamine, which is acylated at the O-benzylhydroxylamine nitrogen with either succinic or acetic anhydride.The resu lting half acid amide or amide, respectively, is subjected to a series of high-yield condensations and reductions that provide desferrioxamine in 45percent overall yield.Finally a desamino analogue of desferrioxamine is prepared in order to demonstrate the synthetic utility of the scheme as applied to desferrioxamine derivatives.
