Different convergentapproaches to the highly oxygenated sesquiterpene natural product saudin (1), has been investigated. Our strategy has included a Michael addition and aldol condensation reaction as key steps. During the synthetic development, we have found serious steric hindrance when an α-Me-substituted alkyl vinyl ketone was used. Such steric hindrance has been overcome by synthesizing the vinyl
