A general method for the synthesis of 2,3-disubstituted indoles is described. The key feature of this method is the amination of aromatic C-H bonds via FeCl2-catalyzed ring opening of 2H-azirines. The method tolerates a variety of functional groups such as Br, F, NO2, OMe, CF3, OTBS, alkenes, and OPiv. The method can also be extended to synthesize azaindoles.

Enolizable ketones react with m-nitroaniline in the presence of strong base such as t-BuOK to give 4- and 6-substituted nitroindoles. The reaction proceeds via oxidative nucleophilic substitution of hydrogen in m-nitroaniline with enolate anions in positions ortho to the amino group giving anionic σH adducts that are additionally stabilized by intramolecular interaction between the amino and the carbonyl group. Spontaneous oxidation of the σH adducts followed by the Bayer type condensation of the produced ortho-aminonitrobenzyl ketones gives 4- and 6-substituted nitroindoles. The scope of this reaction and its basic mechanistic features are discussed.
A novel method of indole ring system construction: One-pot synthesis of 4- and 6-nitroindole derivatives via base promoted reaction between 3- nitroaniline and ketones

Base promoted condensation of ketones RCOCH2R' with 3-nitroaniline results in formation of the corresponding 4- and 6-nitro-2-R-3-R'-indoles. This multistep process apparently includes oxidative nucleophilic substitution of hydrogen in the arom
