合成路线1
该中间体在本合成路线中的序号:(IV)Reductive condensation of 1,4-butanediamine (I) with glyoxylic acid (II) affords 3,8-diazaoctanoic acid (III). Subsequent acylation of diamino acid (III) with 2,3-diacetoxybenzoyl chloride (IV) provides diamide (V). After activation of (V) as the corresponding mixed anhydride with either methyl or isobutyl chloroformate, condensation with ampicillin (VI) yields the title compound.

合成路线2
该中间体在本合成路线中的序号:(II)Acylation of L-lysine (I) with 2,3-diacetoxybenzoyl chloride (II) provides the dibenzoyl lysine derivative (III). After activation of (III) as the corresponding mixed anhydride with isobutyl chloroformate, condensation with alpha-benzyl L-glutamate (IV) yields the dipeptide compound (V). This is further coupled with N-(benzoyloxy) methylamine (VI), via the mixed anhydride with isobutyl chloroformate, to furnish hydroxamate (VII).
