ETUDES DE LIGNANES 7 - SYNTHESES TOTALES DES (+-)-α ET -β-CONIDENDRINES ET DES METHYL (+-)-α ET -β-CONIDENDRALS

Michael addition of the carbanion of the dithian 8 on butenolide, followed by alkylation with the benzylic bromide 11 and regeneration of the ketonic carbonyl group, gave the α,β-disubstituted lactone 13.Reduction of the ketonic carbonyl of the latter usi
