    Project supported by the National Natural Science Foundation of China (Nos. 21072044, 21672052) and the Science and Technology Department of Henan Province (Nos. 14IRTSTHN006, 152300410057).

A visible-light-induced photocatalytic aerobic dehydrogenation of 4-piperidones and 2,3-dihydro-4-quinolones has been developed. By utilizing dicyanopyrazine-derived chromophore (DPZ) as the photocatalyst, the dehydrogenation could provide 2,3-dihydro-4-pyridones and 4-quinolones with satisfactory results (up to 75% yield). The current methodology presents a direct, sustainable and highly atom-economic approach to access these valuable N-containing heterocycles.

Key words: visible light photocatalysis, DPZ, dehydrogenation, pyridone, quinolone
