An efficient and general entry to unsaturated cyclopropane- and lactone-containing oxylipins of marine origin has been designed and applied to the first enantioselectivetotalsynthesis of solandelactone E. The synthesis, which proceeds in a total of 23 steps from commercially available materials, features a diastereoselective acetal-directed cyclopropanation of an electron-deficient diene, a regioselective

The first total synthesis of solandelactone E has been achieved by a novel and convergent strategy that required 23 steps. The synthesis features a diastereoselective acetal-directed cyclopropanation of an electron-deficient diene, a Sharpless asymmetric dihydroxylation, and a [2,3]-sigmatropicrearrangement of a selenoxide intermediate.
