Synthesis method and application of photocatalytic C-3 alkyl-substituted quinoxalin-2(1H)-one compound

The invention relates to the technical field of synthetic methods of quinoxalin-2(1H)-one compounds, in particular to a synthetic method and application of a photocatalytic C-3 alkyl-substituted quinoxalin-2(1H)-one compound. According to the invention, the C-3 alkyl-substituted quinoxalin-2(1H)-one compound is synthesized by using quinoxalin-2(1H)-one, a derivative thereof and substituted sulfonium salt as raw materials, an organic photosensitizer as a photocatalyst, at least one carbonate or nitrogen-containing organic alkali as alkali in an inert gas environment and under the condition of normal temperature and adopting near-blue light to irradiate reaction liquid. The synthesis method disclosed by the invention is simple in preparation process and device, adopts near-blue light as energy, is mild in reaction conditions, and is green and environment-friendly; and the synthesis method is direct alkylation at the C-3 site, and complex pretreatment is not needed, so the method accords with the environmental protection concepts of green chemistry and atom economy.

Visible-light-induced chemoselective reactions of quinoxalin-2(1H)-ones with alkylboronic acids under air/N2 atmosphere

A visible-light-induced chemoselective reactions of quinoxalin-2(1H)-ones with alkylboronic acids in the presence of air (O2) and N2 atmosphere was developed under transition-metal free conditions, providing 3-alkylquinoxalin-2(1H)-ones and 3,4-dihydroquinoxalin-2(1H)-ones, respectively.
