Aza-Heterocycles via Copper-Catalyzed, Remote C-H Desaturation of Amines
{{output}}
The majority of medicines contain a nitrogen atom within a five- or six- membered ring. To rapidly access both such aza-heterocycles, we sought to develop a remote C-H desaturation of amines. Inspired by the Hofmann-Löffler-Freytag synthesis of five-membered ... ...
