In this paper,we report the concise total syntheses of three botryane sesquiterpenoids:dehydrobotrydienal,dehydrobotrydienol,and 10-oxodehydrodihydrobotrydial.The key transformations include tandem Co-tetramethylthiourea-catalyzed Pauson–Khand and 6π-electrocyclization reactions to forge the tricyclic core structure of the botryanes,and further oxidative aromatization and oxidation to complete the total syntheses. 展开更多
