✦ Synopsis


Efficient synthesis of 7-O-methyldehydropinguisenol, a typical pinguisane-type sesquiterpene with a furan moiety, was accomplished by applying palladium-catalyzed 1,7-enyne cycloisomerization for the construction of six-membered ring bearing an exomethylene as well as of adjacent quaternary centers.
