Several di- and trihydroxamate analogues of natural microbial iron chelators have been prepared. The syntheses involved linkage of core structural units, including pyridinedicarboxylic acid, benzenetricarboxylic acid, nitrilotriacetic acid, and tricarballylic acid, by amide bonds to 1-amino-omega-(hydroxyamino)alkanes to provide the polyhydroxamates 1-5. The required protected (hydroxyamino)alkanes

The synthesis of analogs of arthrobactin (5), a microbial iron chelator, and its imide 8 are described. The differentially protected citric acid residue 31 served as the key intermediate in making conjugates having a generalized structure 14 with two representative carbacephalosporin units, 15 and 16. Both conjugates, 49 and 51, showed antibiotic activity, while conjugate 51 obtained from beta-lactam 16 bearing a phenylglycyl side chain was shown to be more effective.
