(λ=210 nm) promoted procedure proceeding in aqueous media at room temperature using ambient air as the oxidant for efficient synthesis of an array of α‐ketoamides of all types using a non‐metal catalyst N‐iodosuccinimide with a loading of 20 mol%. With UV, oxygen in the air was efficiently utilized as the green oxidant, some control experiments were carried out and a plausible mechanism was proposed

microreactor system, carbamoyllithium compounds were successfully generated and used for reactions with electrophiles to give various amides, including α‐ketoamides. The present method could be applied to the three‐component synthesis of functionalized α‐ketoamides using a carbamoyllithium compound, methyl chloroformate, and a functionalized organolithium reagent.
