A diastereoselective synthesis of (1SR,3SR,7RS)-3-methyl-α-himachalene, the sex pheromone of the sandfly, Lutzomyia longipalpis (Diptera: Psychodidae)

Total Synthesis of (±)-Marsupellins A and B via Acetoxymarsupellone Using an Intramolecular Reductive Cyclization of Epoxycyanohydrin Derivative with Cp2TiI

The first total synthesis of C3- and C9-oxidized ent-longipinane-type sesquiterpenoids containing acetoxymarsupellone, marsupellins A and B, has been accomplished. This unique core common to C3- and C9-oxidized ent-longipinane-type sesquiterpenoids was constructed via a new intramolecular reductive cyclization reaction of an epoxycyanohydrin derivative using Cp₂TiI.
