合成路线2
该中间体在本合成路线中的序号：(V)The title compound was originally isolated from the fermentation broths of Streptomyces rubellomurinus. The chemical synthesis of this compound was further described. Treatment of O-benzyl hydroxylamine (I) with TsCl in pyridine afforded N-(benzyloxy)-p-toluenesulfonamide (II). A closely related procedure used O-(p-methoxy-benzyl)hydroxylamine. Diethyl (3-bromopropyl)phosphonate (V) was obtained by alkylation of the sodium salt of diethyl phosphonate (III) with 1,3-dibromopropane (IV). Related procedures used dibutyl phosphonate or 1-bromo-3-chloropropane instead of (III) or (IV). The condensation of protected hydroxylamine (II) with bromide (V) in the presence of NaH furnished adduct (VI). Alternatively, intermediate (VI) was prepared by first alkylation of N-(benzyloxy)-p-toluenesulfonamide (II) with 1,3-dibromopropane (IV) to give (VII), and then condensation of bromide (VII) with the sodium salt of diethyl phosphonate (III). Hydrolysis of (VI) with HCl in HOAc gave rise to 3-(N-hydroxyamino)propylphosphonic acid (VIII). This was finally acetylated with Ac2O in NaOH.
