Development and synthetic application of epoxysilane rearrangement, a novel synthetic use of α,β-epoxysilanes, in which an anion-induced ring-opening of epoxide and Brook rearrangement in the resulting α-silyl alkoxide occur in a tandem fashion to provide a β-siloxy allyl anion, are described. Chirality transfer from epoxides to the position next to a nitrile group by taking advantage of the concerted process of the rearrangement is also reported.
