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.).

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.

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
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.
