A Convenient Synthesis of (24S)-1-α-Hydroxyvitamin D2

A new method was developed for the synthesis of (2R)- and (2S)-2,3-dimethylbutyl p-tolyl sulphone from a chiral sulphinate ester, and applied to the synthesis of (24S)-1α-hydroxyvitamin D2; this new 24-epimer of vitamin D2 has a distinct biological activi
