Blue light: A decarboxylative‐catalyzed Minisci‐type cross coupling reaction of quinoxalin‐2(1H)‐ones with aliphatic carboxylic acids using iridium as photocatalyst is described herein. Varieties of quinoxalin‐2(1H)‐ones could be successfully converted into the alkylated quinoxalin‐2(1H)‐one motifs. The reaction has been successfully applied to the late stage functionalization carboxylic acid‐containing bioactive molecules, and a mechanistic study indicates a radical mechanism. Moreover, preliminary antibacterial evaluation against Magnaporthe grisea showed a promising inhibitory rate.
