The first totalsynthesis of amphiasterin B4, a secondary metabolite previously isolated from Plakortisquasiamphiaster has been achieved. The core structure has been reached according to a highly stereoselective one-pot epoxidation/cyclization of an unsaturated diol. This substrate can be prepared from β,γ-unsaturated diesters readily available from the organocatalyzed protonation of a transient dienol
