Abstract Various substituted oxazolo[5,4-b]pyridines 5a-d have been synthesized by condensation of appropriate hydroxyaminopyridines and aldehydes followed by oxidative cyclization of the resulting Schiff's bases with lead tetraacetate. This method has been extended to the synthesis of the DNA minor groove binding ligands 5e and 5f related to Hoechst 33258 1.
摘要 各种取代的恶唑并[5,4-b] 吡啶 5a-d 已通过适当的羟基氨基吡啶和醛的缩合,然后将所得席夫碱与四乙酸铅氧化环化而合成。该方法已扩展到与 Hoechst 33258 1 相关的 DNA 小沟结合配体 5e 和 5f 的合成。
