The iron-mediated spiroannelation of a 6-aminoindo-line derivative (1-acetyl-6-amino-4,7-dimethoxyindoline) allows an easy access to a tetracyclic subunit (tricarbonylspiro[(η4-4-methoxy-2,4- cyclohexadiene) -1,5′ - (1′- acetyl -2′ ,3′ ,5′ ,6′ ,7′ ,8′ - hexahydro- 4′ ,9′ -dimethoxy[1H]pyrrolo[3,2-g]quinoline)]iron) of the discorhabdin and prianosin alkaloids.
