Abstract
Regioselective Weinreb amidation of the C1 ester of dimethyl pyridazino [4, 5-b] indole-1, 4- dicarboxylate followed by an intramolecular inverse electron-demand Diels–Alder reaction and palladium-catalyzed coupling produced regioselectively protected N6-methylindolo [2, 3- a] pyrrolo [3, 4-c] carbazole (N6-methylstaurosporinone).
