A series of novel amide derivatives of cembranoid neocrotocembraneic acid were designed and synthesized. The antiproliferative activities of these derivatives were evaluated against three human tumor cell lines (the human cervical cancer cell line HeLa, chronic myeloid leukemia cell line K562 and leukemia multidrug-resistant cell line K562/A02). Some of the synthesized compounds exhibited moderate

enantioselective totalsyntheses of (+)-11,12-epoxy-11,12-dihydrocembrene-C 1 and (−)-7,8-epoxy-7,8-dihydrocembrene-C 2, two naturally occurring cembranoxides isolated from tropical marine soft corals, are achieved via a generalapproach by employing an intramolecular McMurry coupling and Sharpless asymmetric epoxidation as key steps from readily available starting materials. The syntheses presented here
