| Outline of Final Research Achievements |
Toward total syntheses of bioactive meroterpenoids berkeleyones, a stereoselective method for the construction of bridged polycyclic systems by a biomimetic polycyclization reaction has been developed. A model study revealed that the desired reaction proceeded in a concerted manner upon treatment of epoxyallylsilanes with diethylaluminum chloride, leading to the regio- and stereoselective formation of bridged polycyclic compounds. The cyclization product having an oxygen functionality at C8 was successfully converted to C3-dehydrated berkeleytrione through a ring-closing metathesis reaction.
