Isoindolinone derivatives are important pharmaceutical building blocks in medicinal chemistry. Isoindolo[2,1-a]quinolines are a class of interesting compounds that possess protective effects against N2-induced hypoxia and inhibitory activities against human topoisomerase II and bacterial DNA-gyrase. The conventional methods for synthesizing these compounds are unsatisfactory because of their harsh
异吲哚啉酮衍生物是药物化学中重要的药物结构单元。异吲哚并[2,1-a] 喹啉是一类有趣的化合物,对 N2 诱导的缺氧具有保护作用,对人拓扑异构酶 II 和细菌 DNA 促旋酶具有抑制活性。合成这些化合物的常规方法因其反应条件苛刻、起始材料复杂和多级纯化程序而不能令人满意。这种炔丙基-异吲哚啉酮核的合成具有基于醛-炔-胺 (A3) 偶联的串联策略,在 Cu(OTf)2 催化下使用 2-甲酰基苯甲酸甲酯、伯芳基胺和末端炔。
