合成路线1

该中间体在本合成路线中的序号：(V)

The reaction of 1-amino-5-nitropentane (I) with benzyloxycarbonyl chloride (A) by means of NaOH in water gives 1-carbobenzoxyamino-5-nitropentane (II), which by reduction with Zn and ammonium chloride in ethanol - water yields 1-carbobenzoxyamino-5-hydroxylaminopentane (III). The reaction of (III) with succinic anhydride (B) by means of NaOH in pyridine water affords 1-carbobenzoxyamino-5-(N-succinylhydroxylamino)pentane (IV), which is cyclized with hot acetic anhydride giving 2-(5-carbobenzoxyaminopentyl)-3,6-dioxotetrahydro-1,2-oxazine (V). The reaction of (V) with the nitroamine (I) by means of sodium methoxide in methanol yields 1-carbobenzoxy-6-hydroxy-16-nitro-7,10-dioxo-6,11-diazahexadecane (VI), which is reduced with Zn and acetylated as before affording 1-carboxybenzoxyamino-6-hydroxy-16-(N-acetylhydroxylamino)-7,10-dioxo-6,11-diazahexadecane (VII).
