A catalytic Fe(III)/Fe(II) redox cycling approach has been examined and applied towards synthesis of a wide range of benzimidazole, bis-benzimidazole and imidazopyridine derivatives from oxidative coupling of aromatic ortho-diamines with aromatic as well as heterocyclic aldehydes bearing different types of substituents. This versatile and convenient method has further proven to be particularly useful
已经研究了催化 Fe(III)/Fe(II) 氧化还原循环方法,并将其应用于通过芳香邻二胺与芳香醛和杂环醛的氧化偶联来合成各种苯并咪唑、双苯并咪唑和咪唑并吡啶衍生物不同类型的取代基。进一步证明,这种通用且方便的方法特别适用于迅速提供许多新型双苯并咪唑类 Hoechst 33 258 类似物,以作为荧光核酸结合探针的潜在开发。这里介绍了三十种不同化合物的成功制备和表征。
