Abstract A novel asymmetricsynthesis of a (3R,5S)-dihydroxyhexanoic ester is described. The ester, which serves as the precursor for generating the side chain of rosuvastatin, is synthesized from d-glucose and subsequently coupled, under Wittig olefination conditions, with a phosphonium ylide derived from an appropriately substituted pyrimidine moiety. The coupling results in the formation of a precursor
