The 5-hydroperoxyfuran-2(5H)-ones 3 are synthesized by acid hydrolysis of the dihydrofurans 1 which are prepared in one-pot procedure by reaction of the corresponding furans 4 with singlet oxygen and methanol. The synthetic method has a wide range of applicability; however, compounds 3 unsubstituted at C-4 cannot be prepared since the corresponding dihydrofurans 1 are not formed.
5-氢过氧呋喃-2(5H)-酮3是通过对二氢呋喃1进行酸水解合成的。这些二氢呋喃1是在一次性反应过程中,通过相应的呋喃4与单线态氧和甲醇反应制备的。该合成方法具有广泛的应用范围;然而,无法制备在C-4位上未经取代的化合物3,因为相应的二氢呋喃1不会形成。
