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.
