Due to the extensive applications of quinolines, the search for selective construction of such products has long been an attractive subject in scientific community. Herein, by developing a new N-doped ZrO2@C supported cobalt nanomaterial, it has been successfully applied as an efficient catalyst for the reductive annulation of 2-nitroaryl carbonyls with alkynoates and alkynones. The catalytic transformation allows synthesizing a wide array of funcitonalized quinolines with the merits of broad substrate scope, good functional group tolerance, excellent hydrogen transfer selectivity, reusable earth-abundant metal catalyst, and operational simplicity. The developed chemistry paves the ways for further design of hydrogen transfer-mediated coupling reactions by developing heterogeneous catalysts with suitable supports.

The dual transition metal-visible light photoredox catalysis for the synthesis of quinoline derivatives by using dioxygen as an oxygen source is developed. By using visible light, the direct oxidative cyclization of aromatic enamines with alkynes or alkenes can be achieved at mild conditions with an aid of copper or palladium catalysts, and a variety of multisubstituted quinoline derivatives could be obtained in good to moderate yields under mild reaction conditions.
