Four flexible macrocycles, such as cTz (1), cTN (2), cPT (3), and cPTN (4), were efficiently synthesized through cyclodimerizing triazo-alkynyl-containing monomers via Cu(I)-catalyzed click reactions with optimized conditions. The starting materials were pyrrole and triazole derivatives containing amine and carboxyl groups, followed by amide coupling to introduce the triazo and alkynyl groups to prepare
四个灵活的大环,如 cTz (1)、cTN (2)、cPT (3) 和 cPTN (4),通过在优化条件下通过 Cu(I) 催化的点击反应环二聚含三重氮炔基的单体而有效合成. 起始原料为含有胺和羧基的吡咯和三唑衍生物,然后通过酰胺偶联引入三重氮和炔基制备环化前体。电喷雾电离质谱 (ESI-MS) 结果表明 cTN (2) 和 cPT (3) 显示出与 c-myb G-四链体结合的能力。因此,cTN (2) 和 cPT (3) 分子可能是抗癌药物发现的潜在先导化合物。
