Thermolysis of 2-acetyl-3,6-diamino-5-methyl-1,4-benzoquinone tosylhydrazones (2a-c) prepared by the reactions of monoaminoquinone tosylhydrazones (1a-c) with the corresponding amines gave 5-hydroxyindoloquinones (5a, b) and related compounds. In the case of 2-acetyl-5-methyl-6-morpholino-3-pyrrolidino-1,4-benzoquinone tosylhydrazone (2e), 7-morpholino-(4e) and 7-hydroxypyrrolo [1,2-α] indoloquinone (5a) were obtained. The mechanism of this reaction, which afforded new indoloquinone ring systems, was investigated.
