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.

Synthesis of 3-alkenyl-1,2,5-triol derivatives, potentially useful intermediates in organic synthesis, is established, which constitutes stereoselective epoxidation of the hitherto hardly accessible dienyl alcohols of the cis,trans stereochemistry followed by Pd-catalyzed reaction with AcOH.
