The synthesis of variously substituted indolo[2,3-c]quinolin-6(7H)-ones was developed via Pd-catalyzed intramolecular C–H arylation. This method highlights a strategy for preparing indoloquinoline precursors bearing versatile functional groups and provides a new approach for the synthesis of antimalarial isoneocryptolepine analogues. The plausible ring closure mechanism was examined with quantum chemical
通过Pd催化的分子内C–H芳基化反应,开发了各种取代的吲哚[2,3 - c ]喹啉-6(7 H)-ones的合成。该方法突出了制备带有多功能官能团的吲哚喹啉前体的策略,并为合成抗疟异异烯油菜碱类似物提供了新方法。通过量子化学计算研究了可能的闭环机理,推测是三角双锥体协同的金属化-去质子化过渡态。
