One-pot Cu-catalyzed tandem aerobic oxidative cyclization for the synthesis of quinolines from 2-vinylanilines/2-arylanilines and 2-methylquinolines via C(sp3)–H/C(sp2)–H bond functionalization has been developed. Dioxygen as an ideal oxidant has been employed for this transformation. The substrates bearing various functional groups perform well in this process and generate the desired products in
一锅铜催化串联好氧氧化环化反应通过C(sp 3)–H / C(sp 2)–H键功能化由2-乙烯基苯胺/ 2-芳基苯胺和2-甲基喹啉合成喹啉。作为理想的氧化剂,已使用二氧进行该转化。带有各种官能团的底物在该过程中表现良好,并以中等至良好的产率产生所需的产物。
