Electrochemical Deoxygenative Amidation of α‐Ketoacids

α‐Ketoacids serve as sustainable acylating agents due to their α‐ketoacid functionality. While decarboxylative amidation under metal, photoredox, or electrochemical catalysis have been established, deoxygenative amidation pathways remain relatively rare—especially electrochemically mediated variants. Herein, we report an electrochemical method for synthesizing N‐aryl ketoamides from α‐ketoacids and arylamines. This approach utilizes direct electron transfer in the presence of electrolyte ions and a phosphine reagent to achieve deoxygenative amidation, preserving both carbonyl groups. The operationally simple and oxidant‐free protocol provides efficient access to diverse ketoamides.

Abstract

α‐Ketoacids serve as sustainable acylating agents due to their α‐ketoacid functionality. While decarboxylative amidation under metal, photoredox, or electrochemical catalysis have been established, deoxygenative amidation pathways remain relatively rare—especially electrochemically mediated variants. Herein, we report an electrochemical method for synthesizing N‐aryl ketoamides from α‐ketoacids and arylamines. This approach utilizes direct electron transfer in the presence of electrolyte ions and a phosphine reagent to achieve deoxygenative amidation, preserving both carbonyl groups. The operationally simple and oxidant‐free protocol provides efficient access to diverse ketoamides.
