, p. 11584 - 11585 (2002)
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.

Total syntheses of (+)- and (-)-cacospongionolide B, cacospongionolide E, and related analogues. Preliminary study of structural features acquired for phospholipase A2 inhibition

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.
