Abstract
(E)-4-Diethoxyphosphonyl-2-methylbut-2-enal was smoothly converted into its O-acetylated or O-triisopropylsilylated (E, E)-enol ethers, which were use d as efficient and (E)-stereoselective five carbon polyvinylogation reagent s of aldehydes, via the corresponding in situ generated potassium or tetrab utylammonium dienolates, respectively.
