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
在高价碘试剂,全氟化醇和呋喃的存在下处理各种含有磺酰基的取代苯胺,会促进正式的脱芳香化[2 + 3]环加成过程,从而以有用的收率产生二氢呋喃二氢吲哚核。此后,这些功能化的系统可用于进一步的转化,从而产生潜在的关键中间体,用于复杂天然产物的全合成。
