Various 3-alkyl-2-nitrobenzo[b]furans were synthesized from common intermediate 2-(2-nitroethyl)phenols via a hypervalent iodine-induced oxidative cyclization, with good to excellent yields. This facile route is able to efficiently functionalize 2-nitrobenzo[b]furans, which are difficult to obtain by classical methods.
由普通的中间体2-(2-硝基乙基)苯酚经高价碘诱导的氧化环化反应合成了各种3-烷基-2-硝基苯并[ b ]呋喃,其收率高到极好。这种简便的途径能够有效地官能化2-硝基苯并[ b ]呋喃,这是传统方法难以获得的。
