Tandem epoxysilane rearrangement/Wittig-type reactions using γ-phosphinoyl- and γ-phosphonio-α,β-epoxysilane

[摘要] Reaction of gamma-phosphinoyl- and gamma-phosphonio-alpha,beta-epoxysilane with a base followed by addition of a ketone or an aldehyde afforded dienol silyl ether derivatives via a tandem process that involves base-induced ring opening of the epoxide, Brook rearrangement, and Wittig-type reaction.
