The present invention relates to a process for the preparation of statins by means of a Julia-Kocienski reaction between an aldehyde and a sulfone derivative in the presence of an alkaline metal alkoxy base. The resulting derivatives are suitable as building blocks for statin type compounds such as cerivastatin, fluvastatin, pitavastatin and rosuvastatin.
