Gallium(III) triflatecatalyzed the rearrangement of 2-substituted vinylepoxides into β,γ-unsaturated carbonyl compounds with high regio- and chemoselectivity (>97/3) in lowcatalystloading (1−5 mol %). The alkyl-substituted trimethylsilylvinyl epoxides gave β,γ-unsaturated ketone, but aryl-substituted vinylepoxides gave the aldehydes instead.
