The naturally occurring δ-hydroxy-γ-lactone (4R,5R)-muricatacin and its nonnatural (4R,5S)-analog are synthesized. The starting achiral allylic alcohols are converted into α,β-epoxy diazomethylketones followed by a stereospecific irradiation reaction of these compounds to give 4-hydroxy-2-alkene esters. Using this method in a sequential manner a successive introduction of stereogenic centers is realized
