Preparation of Tetrahydrofurfuryl Alcohol Derivatives with Electron-Withdrawing Substituents from 4-Acetoxy-1,5-dibromopentane Derivatives by Treatment with Silver Nitrate

Abstract When 4-acetoxy-1,5-dibromopentane derivatives having the electron-withdrawing groups at the 1-position, which were obtained by Cu(I)-catalyzed photochemical addition of 2-acetoxy-1,3-dibromopropane to electron-deficient olefins, were subjected to treatment with silver nitrate, tetrahydrofurfuryl alcohol derivatives with the electron-withdrawing groups at the 5-position were obtained.
