Abstract
The present invention relates to a process for the preparation of a diol sulfone derivative comprising reaction of a halomethyl substrate with a thio-aryl compound to obtain a thio-ether compound, and oxidizing the thio-ether compound to the corresponding sulfone. In case of a chiral halomethyl substrate, the resulting chiral diol sulfone derivative is suitable as a building block for statin type compounds.
