Stollé synthesis
The Stollé synthesis is a method named after the chemist Robert Stollé for the chemical synthesis of indole derivatives. For this purpose, arylamines (e.g. aniline ) are reacted with α-halogenated carboxylic acid chlorides or oxalyl chloride. The resulting α-halogenated arylamide is cyclized by reaction with aluminum trichloride, a reaction which corresponds to an inner-molecular variant of Friedel-Crafts alkylation or Friedel-Crafts acylation .
