Electrochemically driven regioselective construction of 4-sulfenyl-isochromenones from o-alkynylbenzoates and diaryl disulfides

Abstract

Herein, we have developed an electrochemical technique that enables the regioselective construction of 4-sulfenyl-1H-isochromen-1-ones in an undivided cell under external acid, catalyst, oxidant, or metal-free conditions.
