Abstract
An electrochemical synthesis of flavanones via oxa-Michael addition using silver electrode as a sacrifice is reported. 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.
