Abstract
The trinor-guaiane sesquiterpenoid (+/-)-dictamnol 2 was synthesized, in only 6 steps, from photoadduct 5. The crucial step Involved a SmI2- mediated tandem free radical fragmentation/elimination reaction of dii odide 10. Support for the recently revised structure of dictamnol is p resented.
