substances, we have developed a strategy that integrates the synthetic routes to many of its members. The core ringsystems of the xeniolide, xenibellol, and florlide natural products were constructed stereoselectively from an enantioenriched cyclononadienone. The use of the cyclononadiene scaffold, reagent-controlled transannulations, and the parallels of these transformations to possible biosynthetic
