novel and highly efficient copper‐catalyzed tandem synthesis of triazoloquinazolinones is explored. The synthetic strategy involves a sequential one‐pot click reaction followed by aerobic intramolecular CH amidation. Two distinct and important transformations were carried out in one‐pot by employing a single cost‐effective copper catalyst. The milder, rapid and ligand‐free reaction conditions as well
探索了新颖且高效的
铜催化串联合成三唑并
喹唑啉酮。合成策略包括先后的一锅点击反应,然后进行好氧的分子内CH酰胺化反应。通过使用一种具有成本效益的
铜催化剂,在一个锅中完成了两个截然不同且重要的转变。温和,快速和无
配体的反应条件以及更广泛的底物范围是该新颖方案的显着特征。
