A convenient three-step synthetic approach towards 3-alkyl-5-methyl-2[5H]furanones is described. The steps involved in the synthesis are domino primary alcohol oxidation-Wittig reaction, acid-catalysed lactonisation and isomerisation. This synthetic approach has been exploited to synthesise four Streptomyces lactones.
