Synthesis of α,β-unsaturated carbonyl compounds by successive rearrangement and peterson olefination of β′-hydroxy-α,β-epoxysilanes

Abstract

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