Synthesis of 4,7-Dimethoxyindoles Bearing Substituents at the C-5 and C-6 Positions and Studies on their Demethylation Products

Malesani, Giorgio,Galiano, Fabio,Ferlin, Maria Grazia,Masiero, Sergio

, p. 563 - 569 (2007/10/02)

Syntheses of some 4,7-dimethoxyindoles bearing methyl, amino or acetamido groups at the C-5 and C-6 positions were investigated.The presence of these substituents made possible the isolation of the corresponding 4,7-dihydroxyindole derivatives obtained by long reflux with aluminium chloride in benzene solution.
