Ozonolysis followed by acetylation of the (3S,3aS,5aR,9R,9aS,9bS)-5a-hydroxymethyl-2-methoxy-3,9-dimethyl-2,3-decahydronaphtho<1,2-b>furan (7) derived from (-)-α-santonin gave an unexpected product, (3S,3aS,6R,7S,7aS)-7-<(S)-2-formylethyl>-2-methoxy-3-methyloctahydrobenzofuran-6-spiro-3'-furan-5'-one (13), which served as the key intermediate for the synthesis of (+)-deoxyvernolepin (2) and related unsaturated lactones (4)-(6).Some unsaturated lactones obtained were submitted to a preliminary test for antitumour activity.
