β-epoxyketones, readily prepared in a chiral form by using the Sharpless kinetic resolution of γ-trimethylsilyl secondary allylic alcohols as a key reaction, with Grignardreagents proceeds highly diastereoselectivity to afford opticallyactive γ-trimethylsilyl-β,γ-epoxy tertiary alcohols.

Kineticresolution of (E)-1-trimethylsilylalk-1-en-3-ol by the Sharplessprocess, which proceeds with very large rate differences for the two isomers, combined with the reactivity of epoxysilyl compounds affords a practical, efficientmethod for preparation of fourpossiblestereoisomers of secondaryallylicalcohols.
