Reaction of -chloroalkyl ketones with 1,3-dinitrobenzenes provides 2,4-dinitrobenzyl ketones which when reduced with tin(II) chloride form 6-nitro derivatives of 1-hydroxyindoles. An alternative approach is the condensation of 2,4- and 2,6-dinitrotoluenes

Process for producing indole compound

Page/Page column 8, (2008/06/13)
There is provided a novel process for producing an indole derivative which comprises cyclizing 2-nitrobenzylcarbony compound in the presence of a catalyst comprising a Group VIII metal of the Periodic Table, characterized by conducting the cyclization in a gas atmosphere containing carbon monoxide. The process enables an indole compound to be selectively produced in a high yield from 2-nitrobenzylcarbonyl compound, and hardly yields an indoline compound as a reduction by-product that has been a problem in the catalytic hydrogenation method employing a noble metal catalyst. The indole derivative produced by the present process is useful for various fine chemical intermediates including compounds and physiologically active substances such as pharmaceuticals and agrochemicals.
Synthesis of 4- and 6-substituted nitroindoles

, p. 347 - 358 (2007/10/03)
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.
