β,γ‐Unsaturatedaldehydes with all‐carbon quaternary or tertiary α‐centers were rapidly assembled from ketones through a unique synthetic operation consisting of 1) C1 homologation, 2) Lewis acid mediated epoxide–aldehyde isomerization, and 3) electrophilic trapping. The synthetic equivalence of a vinyl oxirane and a β,γ‐unsaturatedaldehyde is the key concept of this previously undisclosed tactic

α,β-Unsaturated carbonyl compounds and esters, cyclopropyl ketones, β-diketones, Schiff’s bases, and nitriles were irradiated in several alcohols in the presence of titanium(IV) chloride or uranyl chloride. In the titanium(IV) chloride-catalyzed reactions, the α-carbon atom of the primary alcohols underwent a bond formation, generally with the C=X (or C≡N) carbon atom of the substrates, while the bond
