, p. 2785 - 2790 (2007/10/02)
The α,β-dibromo ethers 2, in situ generated from the vinyl ethers 1 and bromine, react with the allylsilanes 3 in the presence of ZnCl2 to give the β-bromo ethers 4.Treatment of 4 with Na in diethyl ether yields 1,4-dienes 5 in 62-79percent overall yield.Key Words: Enol ether / Allylsilane / Bromo ether / 1,4-Diene / Alkoxyalkylation
