Synthesis of desferrioxamine B and analogs and homologs thereof beginning with O-protected, N-protected hydroxylamine, which is N-alkylated to produce a protected N-4-cyanoalkylhydroxylamine which is acylated with a suitable anhydride. The resulting half-acid amide is subjected to a series of high yield condensations and reductions which provide desferrioxamine B in high overall yield. Alternatively, polyether analogs of desferrioxamine B can be prepared by reacting an activated polyether with the O-protected, N-protected hydroxylamine and subjecting the resulting product to a series of similar steps.
使用O-保护的、N-保护的
羟胺开始合成去
铁去氧胺B及其类似物和同系物,该
羟胺被N-烷基化以产生一种受保护的N-4-
氰基烷基
羟胺,然后使用适当的酸酐酰化。所得到的半酸酰胺经过一系列高产率的缩合和还原反应,以高总收率产生去
铁去氧胺B。另外,可以通过将活性聚醚与O-保护的、N-保护的
羟胺反应,并将所得产物经过一系列相似的步骤,制备去
铁去氧胺B的聚
