A catalyst‐free oxidative decyanation–amidation reaction is developed for the synthesis of α‐ketoamides using β‐ketonitriles, primaryamines, and hydrogen peroxide sodium carbonate adduct (Na2CO3·1.5H2O2). This method is a valuable and simple strategy for the decyanation reaction.

The direct oxidative synthesis of α-ketoamides via anodic oxidation was developed by using dioxygen as a reactant under mild conditions. This methodology has a broad substrate scope (aromatic amines, aliphatic amines and ammonium acetate) and opens up an interesting and attractive avenue for the synthesis of α-ketoamide derivatives.
α-Ketoamide moieties, as privileged units, may represent a valuable option to develop compounds with favorable biological activities, such as low toxicity, promising PK and drug-like properties. An efficient silver-catalyzed decarboxylative acylation of α-oxocarboxylic acids with isocyanides was developed to derivatize the α-ketoamide functional group via a multicomponent reaction (MCR) cascade sequence

A wide range of N-tosyl α-ketoamides underwent transamidation with various alkyl and benzyl amines in the absence of a catalyst or base at room temperature. On the other hand, transamidation in N-Boc α-ketoamides was achieved in the presence of Cs2CO3.
