The development of an asymmetric route for the synthesis of α,β-butenolide building blocks, starting from commercially available D -mannitol, is described. The devised route was applied to a synthesis of the (S)-(-)-enantiomer of the antiviral natural product umbelactone, together with the construction of other synthetically useful lactone structures.
