reaction provides an efficient route to α‐ketoamides compounds, which are ubiquitous structural units in a number of biologically active compounds. N‐substituted anilines are suitable substrates for this transformation. Two CH bonds as well as one CH and one NH bond are cleaved in this reaction. Molecular oxygen (1 atm) is used as the oxidant and the reaction involves dioxygen activation.

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.
