Abstract

Summary: The cathodic cyclocoupling of 1, 3-dienes 1 with aliphatic esters 2 is promoted by a magnesium electrode and yields homologs of 3-cyclopentenol. Under similar reaction conditions, the coupling of styrenes with 2 affords 2-phenylcyclopropano1 derivatives, and this coupling reaction has been successfully applied to the synthesis of ar-dihydroturmerone and curcumone.
