Abstract
Three-component coupling between acyl chlorides, diazonium salts, and alcohols or amines allows the formation of α-hydrazono carboxylic acid derivatives which may be directly converted into indoles by a Fischer-type cylization.
Key words
indoles - Fischer - Japp-Klingeman - diazonium - hydrazone - acid chloride - multicomponent reaction
