Tandem formation of an unsaturated zirconacycle, insertion of methallyl carbenoid, and addition of an aldehyde provides a rapid synthetic route to several linear terpenoid and terpene–polyketide natural products.

Abstract Nine new sesquiterpenes related biosynthetically to ipomeamarone, the well-known sweet potato phytoalexin, have been isolated from Ceratocystis fimbriata -infected sweet potato root tissue and the structures determined. Their biosynthetic relationship with previously identified furanoterpenes is discussed.
