Formation of enaminoketones, enaminocrotonate, and aminomethylenemalonate from 2,3-dimethyl-5-methoxy-6-aminoindole occurs significantly less easily than for the 7-methoxy analog. A similar dependence is observed in the reaction of enamines to the corresponding pyrroloquinolines independently of the cyclization conditions.
