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.

The first totalsynthesis of optically active coraxeniolide-A (1a) and 4-epi-coraxeniolide-A (1b) is described. The approach is highly stereoselective and flexible in the preparation of a wide variety of members of the xeniolide family. The use of the Grob-fragmentation was pivotal for the stereospecificelaboration of the nine-membered ring. Coraxeniolide-A (1a) was synthesized in 28 steps by using
