A method for making an indole compound includes transition metal-catalyzed arylation of a hydrazone to form an aryl hydrazone, hydrolysis of the aryl hydrazone to form an aryl hydrazine, and acid catalyzed cyclization of the aryl hydrazine to form the indole compound.

Eine Methode für das Bilden eines Indolmittels schließt Übergang Metall-katalysierte Arylierung eines Hydrazons ein, um ein Aryl- Hydrazon, Hydrolyse zu bilden des Aryl- Hydrazons, um ein Aryl- Hydrazin und Säure katalysierte Zyklisierung des Aryl- Hydrazins zu bilden, um das Indolmittel zu bilden.
