A high-yielding, copper-catalyzed dearomatization reaction of indole from 2-methylindole-derived oxime acetates was realized, providing access to structurally novel spiro[indoline-3,2′-pyrrolidine] derivatives in 67–98% yields. When the C-2 position of the indole was not substituted, azacarbazole derivatives were obtained in moderate yields. This transformation provides an efficient approach to access nitrogen-containing spiroindolenine and azacarbazole derivatives with wide substrate scope. (Figure presented.).

We report the cyclization of 3-substituted N-acetylindoles for the straightforward synthesis of 3,3-spiroindolines via the Friedel-Crafts reaction of an appended aryl group or the formal [2 + 2] cycloaddition of an appended alkene. Our strategy involves a

An effective one-pot synthesis of β-indolylketones from saturated ketones and indoles was developed. It is noteworthy that this methodology has a good functional group tolerance (alkyl, nitro, halogen, hydroxyl, methoxyl, carboxyl and ester) and is of great significance to the preparation of many indole heterocycles.
In situ generation of Iron(iii) dodecyl sulfate as Lewis acid-surfactant catalyst for synthesis of bis-indolyl, tris-indolyl, Di(bis-indolyl), Tri(bis-indolyl), tetra(bis-indolyl)methanes and 3-alkylated indole compounds in water

Iron(iii) dodecyl sulfate as Lewis acid-surfactant catalyst was prepared in situ and effectively used in the synthesis of bis(indolyl)methanes and Michael reactions of indoles with α,β-unsaturated carbonyl compounds in water. Also, this method was used for the synthesis of 1,1,3-tri-indolyl compounds, producing good to excellent yield at room temperature.
