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

The chiral enones 4 and ent-4 have been synthesized enantiomerically as configurationally stable compounds that can be used for the synthesis of caryophylloids. For instance, ent-4 has been converted to the marine natural product coraxeniolide A.
