Disclosed is a synthesis of desferrioxamine B and analogs and homologs thereof beginning with the generation of the O-protected N-(4-cyanobutyl)hydroxylamine which is acylated at the O-benzylhydroxylamine nitrogen with either succinic or acetic anhydride. The resulting half-acid amide or amide respectively, is subjected to a series of high yield condensations and reductions which provide desferrioxamine B in 45% overall yield. Finally, a desamino analog of desferrioxamine is prepared in order to demonstrate the synthetic utility of the scheme as applied to desferrioxamine derivatives.
本发明公开了一种去铁胺 B 及其类似物和同系物的合成方法,首先生成 O 保护的 N-(4-氰基丁基)羟胺,然后用丁二酸酐或乙酸酐在 O-苄基羟胺氮上酰化。生成的半酸酰胺或酰胺分别经过一系列高产率的缩合和还原反应,最终得到总产率为 45% 的去铁胺 B。最后,还制备了去铁胺的去氨基类似物,以证明该方案在去铁胺衍生物合成方面的实用性。
