Abstract α ‐Ketoamides are privileged chemical entities featuring a carbonyl group bonded to an amide. Bearing two pronucleophilic and proelectrophilic sites, this structural scaffold exhibits distinct properties unparalleled biological activity. Owing its wide application in medicinal, agricultural, synthetic chemistry, methods for assembling moiety ever‐growing demand. With the increasing focus on green synthesis, traditional routes ‐ketoamides have faded recent years giving rise development of photocatalytic, electrosynthetic, microwave‐assisted catalytic protocols. We hereby provide comprehensive critical summary all advancements witnessed field from 2016 present.
