Diverse Tandem Cyclization Reactions of o‑Cyanoanilines and Diaryliodonium Salts with Copper Catalyst for the Construction of Quinazolinimine and Acridine Scaffolds

Two cyclization modes are realized to produce different nitrogen-containing heterocycles, i.e., quinazolin-4­(3H)-imines and acridines by assembling o-cyanoanilines and diaryliodonium salts via tandem reaction pathways.本研究实现了两种环化模式，以邻氰基苯胺与二芳基碘鎓盐为起始原料，经由串联反应路径合成得到两类不同的含氮杂环化合物——喹唑啉-4(3H)-亚胺（quinazolin-4(3H)-imines）与吖啶（acridines）。
