Unusual benzofuranoid neolignans from Licaria chrysophylla 

 -  PhytoChemistry, 25(11), p.2609-2612, 1986 .
<br/><br/> Trunk wood, bark and fruit calyx of Licaria chrysophylla contain eight neolignans which differ from the normal benzofuranoid types by showing 7.1',8.0.2' (rather than 8.1',7.0.2')linkages between the propenylphenol and allylphenol derived moieties. The fundamental chrysophyllon I types, with the allyl at C-1', can rearrange to chrysophyllon II and III types, with the allyl respectively at C-5' and O-4'.
