Electrosynthesis of Flavanones via oxa-Michael Addition Using Sacrificial Electrodes

Abstract

Herein, we report an electrochemical synthesis of Flavanones via oxa-Michael addition using silver electrode as a sacrifice. This electrosynthetic system showed good yields, broad substrate scope and good functional group tolerance. Additionally, the method proved to be applicable on a gram scale. Several studies were carried out to elucidate the reaction mechanism, such as control reactions, cyclic voltammetry and theoretical studies, allowing the proposal of a plausible pathway for this transformation.
