Revised structure for a neolignan from Brucea javanica
摘要:
On the basis of H-1 and C-13 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-6'-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. (C) 1998 Elsevier Science Ltd. All rights reserved.
