This article describes the rapid and diversified synthesis of pyrrolidinyl triazoles for the discovery of mitochondrial permeability transition pore (mPTP) blockers. The 1,3-dipolar cycloaddition of ethynyl trifluoroborate with azidopyrrolidine produced a key intermediate, triazolyl trifluoroborate 4, which subsequently underwent a Suzuki–Miyaura coupling reaction to afford a series of 1,4-disubstituted
本文介绍了用于发现线粒体通透性过渡孔(mPTP)阻滞剂的吡咯烷基三唑的快速合成方法。乙炔基三氟硼酸酯与叠氮基吡咯烷的1,3-偶极环加成反应生成了一个关键中间体三氟三硼酸三唑基4,随后进行了Suzuki-Miyaura偶联反应,得到了一系列1,4-二取代的三唑2。这些衍生物的后续生物学评估表明,与先前报道的肟类似物1相比,2ag和2aj是最有效的mPTP阻断剂,表现出出色的细胞色素P450(CYP)稳定性。。本工作清楚地表明1,2,3-三唑可用作稳定的肟代用品。此外,这表明通过有机三氟硼酸酯的偶联反应进行的后期多样化适于快速发现生物活性分子。
