Alkoxydienylstannanes via metalation of α,β-unsaturated and α-phenyl acetals were analyzed. Treatment of α,β-unsaturated and α-phenyl acetals with an equimolar mixture of butyllithium and potassium tert-butoxide gave α-metalated 1,3 dienes and vinyl ethers that readily react with chlorotributyltin affording (Z)-functionalized alkoxyvinylstannanes. Stille cross-coupling reaction between these reactants and allyl bromide, iodobenzene, or benzoyl chloride produced derivatives that can be converted into carbonyl compounds according to an umpolung approach.
