The enantioselective synthesis of (−)-(5S,7R)-Tarchonanthuslactone, a substituted δ-lactone isolated from a compositae, is described. The main feature of this short synthesis is the stereoselectivereduction of a β,δ-diketosulfoxide affording in 6 steps the chiral central part of the molecule, a syn-1,3-diol unit.
