A formal totalsynthesis of the marine natural product xestoquinone (5) based upon FRT reactionstrategy is accomplished by preparation of the pentacyclic furan 6, an advanced key intermediate in Harada's previous totalsynthesis of this target.
An effective synthesis of furanohydrophenanthrene ring system, as an intermediate toward furanoid spongiaditerpenes syntheses, was accomplished using a furan ring transfer reaction, followed by bis-annulation with 1,7-octadien-3-one,
