A strategy for the synthesis of chiral 5-(1-hydroxyalk-2-enyl)-5H-furan-2-ones and its application to the total synthesis of (-)-muricatacin, in four steps and 37% overall yield from (R,R)-hexa-1,5-diene-3,4-diol, are described. The key synthetic step in this approach is a highly regioselective and stereoselective tandem ring-closing/cross metathesis reaction in which both lactone formation and alkyl
