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.
各种 3-烷基-2-硝基苯并呋喃通过高价碘诱导的氧化环化反应从常见的中间体 2-(2-硝基乙基)苯酚合成,产率良好至优秀。这种简单的方法能够有效地官能化 2-硝基苯并呋喃,这是通过经典方法难以获得的。
