The racemic tetrahydroanhydrodesoxyaucubigenin, one of the derivatives from a glycoside, aucubin, has been synthesized using cis-cis-2-(2′-hydroxyethyl)-5-methoxycarbonylcyclopentane-carboxylic acid δ-lactone as an intermediate. 6,7-Dimethoxycarbonyl-2-oxa-bicyclo[3.3.0]-octane has also been synthesized, and the mechanism of the base-catalyzed rearrangement of the naturally-derived tetrahydroanhydroaucubigenin
