WebApr 1, 2024 · The Fischer Indole Synthesis’s Main Features include: The indole formation can be carried out in one pot, as the intermediate aryl hydrazones need not be isolated. Two region-isomeric 2,3-disubstituted indoles are provided by unsymmetrical ketones with region-selectivity depending on medium acidity, hydrazine substitution, and steric effects. WebFischer Indole Synthesis. In 1883, E. Fischer and F. Jourdan treated pyruvic acid 1-methylphenylhydrazone with alcoholic hydrogen chloride and generated 1-methylindole-2-carboxylic acid. Preparing indoles by heating the arylhydrazones of either aldehydes or ketones in the presence of a protic or Lewis acid is now known as the Fischer indole ...

The Fischer indole synthesis is a chemical reaction that produces the aromatic heterocycle indole from a (substituted) phenylhydrazine and an aldehyde or ketone under acidic conditions. The reaction was discovered in 1883 by Emil Fischer. Today antimigraine drugs of the triptan class are often synthesized by this method.
