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.
当 4-乙酰氧基-1,5-二溴戊烷衍生物在 1-位具有吸电子基团时,通过 Cu(I)-催化 2-乙酰氧基-1,3-二溴丙烷与缺电子烯烃的光化学加成获得, 用硝酸银处理,得到在 5-位具有吸电子基团的四氢糠醇衍生物。
