Abstract

The protecting-group-free total synthesis of (+)-clavulatriene A has been achieved. Key features of the synthetic strategy include the development of a novel strategy for the practical synthesis of α-cyperone, and a one-pot palladium-catalyzed reductive desulfonylation and deacetoxylation reaction. Furthermore, the total synthesis described in this study allowed for the determination of the absolute configuration of (+)-clavulatriene A.
