Abstract
The structures of new extractives from the tubers and aerial parts of Eupomatia bennettii F. Muell. have been assigned as follows: eupomatenoid-15, 2-(4'-methoxyphenyl)-3-methyl-5-(E)-propenylbenzofuran (1); eupomatenoid-16, 7-methoxy-2-(4'-methoxyphenyl)-3-methyl-5-(E)- propenylbenzofuran (3); eupomatenoid-17, 5-allyl-7-methoxy-2-(4'- methoxyphenyl)-3-methylbenzofuran (5); eupomatenoid-18, 5-allyl-2- (3',4'-dimethoxyphenyl)-7-methoxy-3-methylbenzofuran (6). Eupobennettin was shown to be (2'a,3'a,4?ß,5'a)-5-[3',4'-dimethyl-5'-(3',4',5'-trimethoxyphenyl)tetrahydrofuran-2'-yl]-2,3-dimethoxyphenol (7). Spectroscopic studies and a biomimetic synthesis proved that bennettinone was 2-(4'-allyl-2'-methoxyphenoxy)-1-(3',4'-dimethoxyphenyl)propan-1-one (10).
