Synthesis of Lactones via Electrochemical Sequential Oxidative Process

Abstract

Herein, we unveil a novel electrochemical oxidative strategy that facilitates the synthesis of lactones from 2‐arylbenzaldehydes and 2‐arylbenzoic acids. Crucially, our method allows for the convergent synthesis of lactones from the combinations of the respective 2‐arylbenzaldehyde and 2‐arylbenzoic acid as starting material, owing to the oxidative process's compatibility within our electrochemical setup. This approach offers a robust and versatile pathway to construct various dibenzopyranones type lactone compounds through an environmentally considerate and economically advantageous process.
