Treatment of various substituted anilines containing a sulfonyl group in the presence of a hypervalent iodine reagent, a perfluorinated alcohol and furan promotes a formal dearomatizing [2 + 3] cycloaddition process, leading to a dihydrofuranoindoline core in useful yields. Thereafter, these functionalized systems can be used for further transformations, yielding potential key intermediates for the total synthesis of complex natural products.
在高价碘试剂、全氟醇和呋喃存在的情况下,对各种含有磺酰基的取代苯胺进行处理,可促进一种形式上的去芳构化[2 + 3]环加成过程,以可观的产率得到二氢呋喃并吲哚啉核心结构。此后,这些功能化体系可用于进一步转化,生成用于复杂天然产物全合成的潜在关键中间体。
