Abstract

Abstract 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.
