Abstract

Upon transmetallation (BuLi/THF/− 70°C), these new reagents afford α-ethoxybutenyllithiums, which when treated at − 70°C with allyl halides or carbonyl compounds give dihomoallyl ethers or homoallyl monoethers of α-glycols. The latter compounds upon acidic treatment afford α,β- or β,γ-enones, depending on the structure of the substrate and on the experimental conditions. ... Les α-éthoxybutényltributylétains sont aisément synthétisés par réaction ...
