Abstract

original image

Direct evidence: The existence of methoxy radical species formed during an anodic oxidation in MeOH on a boron-doped diamond (BDD) electrode was confirmed by ESR spectroscopy. Effective production of a neolignan, licarin A, was accomplished by the BDD-mediated anodic oxidation protocol (see picture).
