From intermolecular alcohol additions on a double bond to electrocyclizations of non-activated γ, δ-unsaturated alcohols: An easy synthesis of tetrahydrofurans

Article abstract of DOI:10.1016/S0040-4039(97)00081-6

Tetrahydrofurans have been synthesized in high yields through an electrocyclization reaction, by simple treatment of non activated γ, δ- or β, γ-unsaturated alcohols with an acidic resin (Amberlyst H-15) in CH₂Cl₂ at room temperature
