Herein we report on the development of a metal-free oxidative annulation reaction of 1,6-enynes, leading to 4-carbonylquinolines by using dioxygen as a green sustainable oxidant. Key advances include the use of readily available tert-butyl nitrite (TBN) to promote radical annulation of 1,6-enynes and easy-to-handle reaction conditions. Preliminary mechanistic studies including radical capture reactions and isotope labelling experiments are also conducted. (Figure presented.).

A novel copper-catalyzed oxidative cyclization of enynes and in situ formed enynes leading to 4-carbonyl-quinolines by using dioxygen as an oxygen source has been developed.
