6H-isoindolo[2,1-α]indol-6-ones were developed. In the first protocol, 6H-isoindolo[2,1-α]indol-6-ones were prepared from 2-(2-iodophenyl)-1H-indoles via palladium-catalyzed intramolecular aminocarbonylation. The second involves intermolecular carbonylation of indoles with iodobenzenes followed by intramolecular cross-dehydrogenative-coupling.
开发了两种简便的制备6 H-异吲哚并[2,1-α]吲哚-6-的方法。在第一协议,6 ħ -isoindolo并[2,1-α]吲哚-6-酮从2-(2-碘苯基)-1制备ħ通过钯-催化的氨基羰基化的分子内-indoles。第二种涉及吲哚与碘苯的分子间羰基化,然后进行分子内的交叉脱氢偶联。
