We describe here a new metal-free route for the synthesis of 3-nitroindoles by the nitrative cyclization of N-aryl imines with tert-butyl nitrite. The radical transformation allows the assembly of the indole framework through oxidative cleavage of multi C-H bonds, a nitration, cyclization and isomerization cascade.
我们在此描述了一种通过亚硝酸叔丁酯对N-芳基亚胺进行硝化环化反应来合成3-硝基吲哚的无金属新方法。这种自由基转化反应通过多碳氢键的氧化裂解、硝化、环化和异构化级联反应实现了吲哚骨架的构建。
