Intermolecular cycloaddition reaction of unactivated alkenes and o-quinone methides generated by electrochemical oxidation: a proposed biomimetic approach to the euglobal skeletons
Abstract
Electrochemical oxidation of o-[1-(phenylthio)alkyl]phenois in lithium perchlorate–nitroalkane gives corresponding o-quinone methides, which are trapped by unactivated alkenes to form chromanes including euglobal skeletons.
