Total synthesis of (+)-cacospongionolide B was achieved. The synthesis involved highly stereoselective C-glycosidation of a glycal derived from D-arabinose with 3-furyl boronic acid in the presence of a palladium catalyst and S-alkyl Suzuki-Miyaura coupling of in situ generated alkylborane prepared by the reaction of vinyl trans-decaMn with alkenyl triflate.

The total syntheses of the antiinflammatory marine sponge metabolites (+)-cacospongionolide B and E are described. The pivotal steps in the synthetic route include a three-step sequence that couples the two main regions of the natural product, as well as generates the side chain dihydropyran ring. The activity of the synthetic analogues against bee venom phospholipase A 2 suggests that the cacospongionolides have enantiospecific interactions with the enzyme that may be independent of the γ- hydroxybutenolide moiety.

The first total synthesis of the antiinflammatory marine sponge metabolite (+)-cacospongionolide B has been accomplished in 12 linear steps. The pivotal transformations include a three-step sequence coupling the two main regions of the natural product as well as generating the side chain dihydropyran ring. The activity of the synthetic analogues against bee venom phospholipase A2 suggests that cacospongionolide B has an enantiospecific interaction with the enzyme that is independent of the γ-hydroxybutenolide moiety.
