This invention provides a novel method for the preparation of optically active arylalkylsulfone derivatives, having a chiral center in the alkyl moiety in either the (R)- or the (S)-configuration. These optically active sulfones find use in the stereospecific synthesis of steroid or vitamin D compounds having chiral center at either carbon 24 or carbon 25 of the side chain.
