Total synthesis of solandelactones E and F, homoeicosanoids from the hydroid Solanderia secunda.
Asymmetric total syntheses of solandelactones E and F confirmed that hydroxyl configuration at C11 in these oxylipins had been misassigned and that the stereochemistry at this center should be reversed. Key steps in the synthesis involved a Nagao asymmetric acetate aldol reaction, a directed Simmons-Smith cyclopropanation, a Holmes-Claisen rearrangement to establish the unsaturated octalactone, and a Nozaki-Hiyama-Kishi coupling to connect two major fragments at C11-C12.
