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

Structures and absolute configurations are established for five new lignans isolated from the wood of the New Zealand podocarp Dacrydium intermedium Kirk.X-ray crystallography has been used to confirm the structure of one of the new lignans.Structures for two further inseparable lignans are provisionally assigned.The structure of one of three lignans previously isolated from the wood is revised.
