Chemistry of the Podocarpaceae. LXIX. Further Lignans from te Wood of Dacrydium intermedium

Abstract

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.
