ln the previous paper (l), we have reported an efficient anion-induced intramolecular cyclizatian of the epoxy sulfide ,l\_ leading to the fourteen-membered ring compound ,2\_. We have extended our study starting from 2 to induce the other functionalities incorporated in the naturally occurring cemb
Stereoselective synthesis of cubitene (11, a novel diterp-ene isolated from defense secretion of termites, has been accomplished using an intramolecular reaction of a-sulfenyl carbanion vi th epoxide. Hydride reduction of the ketone 11 obtalned by Claisen rearrangement occurred in unexpectedly high
