This paper describes the synthesis of four aryl amide-based macrocycles through the 1 + 1 formation of two 1,2,3-triazole units by click chemistry. Two series of aryl amide-based precursors that bear two azide or acetylene units have been prepared. Intramolecular hydrogen bonding has been utilized to induce them to adopt a U-styled conformation, which remarkably promotes the macrocyclization of two
本文介绍了通过两个1 + 1形成四个芳基酰胺大环的合成 1,2,3-三唑通过点击化学来确定单位。两个系列的基于芳基酰胺的前体带有两个叠氮化物 或者 乙炔单位已经准备好了。分子内氢 结合已被用来诱导它们采用U型构象,这显着促进了两个结构匹配的前体的大环化。
