The complex diterpenoid (+)-ingenol possesses a uniquely challenging scaffold and constitutes the core of a recently approved anti-cancer drug. This full account details the development of a short syn
The tricyclic core of vibsanin E was constructed without the use of a protecting group in six steps. The El Gaïed Baylis−Hillman variant was key to allowing the Brønsted acid induced tandem cyclizatio
Total syntheses of (±)-guanacastepenes N and O were accomplished with 2-cycloheptenone as starting material. The six- and five-membered rings of the core [5, 7, 6] ring skeleton were constructed with
Havellockate (1) was isolated from the soft coral Sinularia granosa located on the Havellock island in the Indian Ocean. This highly compact and polyoxygenated marine diterpene bears a cis-fused hydri
Syntheses of two natural products derived from the ent-kaurene kaurenoic acid are described for the first time using regio- and diastereoselective oxidations. Palladium- and manganese-mediated oxidati
