Abstract

A three-component Minisci reaction coupling of 1,3-dicarbonyl compounds with vinyl ethers and quinolines or isoquinolines under visible light is developed. The 1,3-dicarbonyl compound undergoes single-electron oxidation to afford an electrophilic 1,3-dicarbonyl radical under visible light irradiation. Due to the polarity of the free radical, the electrophilic radical adds to the electron-rich olefin to afford the nucleophilic radical. It coupled with the heteroarene to afford the three-component coupling products.
