磺酰基吲哚与保护的β-硝基酮反应得到相应的3-(2-硝基烷基)吲哚,在酸性条件下,其经历一系列级联过程,最终导致不对称的1,4-二取代的咔唑。
Reaction of sulfonylindoles with protected beta-nitro ketones affords the corresponding 3-(2-nitroalkyl) indoles that, under acidic conditions, undergo a sequence of cascade processes finally leading to unsymmetrical 1,4-disubstituted carbazoles.
