When 1,5-dibromopentane derivatives having the electron-withdrawing groups at one terminus, which were obtained by Cu(I)-catalyzed photochemical addition of 1,3-dibromopropanes to electron-deficient olefins, were subjected to treatment with silver nitrate, tetrahydropyran derivatives with the electron-withdrawing groups at the α-position to the oxygen atom were obtained.
