Kineticresolution of β-trimethylsilyl allylicalcohols by the Sharplessprocess proceeds with synthetically statisfactory rate differences for the two enantiomers, thus providing a practical, effecient method for preparation of both enantiomers of erythro-epoxy secondaryalcohols with high optical purity.

The reaction of β′-hydroxy-α,β,-expoxysilanes with boron trifluoride–diethyl ether results in rearrangement of the epoxysilane skeleton followed by Petersonolefination, leading to αβ-unsaturated carbonylcompounds.
