Revised structure for a neolignan from Brucea javanica



Revised structure for a neolignan from Brucea javanica



Phytochemistry 49(7): 2125-2128



On the basis of 1H and 13C NMR spectral comparison with natural and synthetic compounds, the neolignan isomers isolated from Brucea javanica for which unusual 8-O-6'-structures were proposed have been reassigned to the conventional 8-O-4'-structures (erythro and threo-guaiacylglycerol-beta-coniferyl ether), respectively. Thus far, there is no evidence for the existence of 8-O-6'-neolignans in nature.
