An expedient and simple synthetic approach to pitava statin and rosuvastatin final intermediates is described. The presented approach consists of completely stereoselective Julia-Kocienski olefination step (E/Z up to 300:1) between lactonized statin side-chain precursor and sulfone derivative of the corresponding pyrimidine and quinoline heterocyclic cores. The desired O-TBS protected statin lactones were isolated in 66-71% yield and high >97% purity (HPLC). Georg Thieme Verlag Stuttgart. New York.
