Compounds of formula (I) are antibacterial agents wherein: R3 and R4, taken together with the carbon atoms to which they are respectively attached, form an optionally substituted saturated carbocyclic or heterocyclic ring of 5 to 16 atoms, which may be benz-fused or fused to a second optionally substituted saturated carbocyclic or heterocyclic ring of 5 to 16 atoms; and R1 and R2 are as defined in the specification.

The reaction between alkylsuccinic anhydrides (III) and O-benzylhydroxylamine yields the acids (VI). These acids (VI) may be coupled with amino-amides (II) by the mixed anhydride procedure, giving a mixture of the racemates (VIII) and (IX). Hydrogenolysis of the O-benzylhydroxamic acids (VIII) and (IX) yields structuralanalogues [(X) and (XI)] of the natural antibioticactinonin (I).
