Tandem Photocatalyst-Free Visible Light Aryl Azidation-Intramolecular C-H Amination: One-Pot Access to Carbazoles and Indoles from Areneazo-2-(2-nitro)propanes

초록

The visible light-induced one-pot tandem photolysis of areneazo-2-(2-nitro)propanes was achieved to give carbazole and indole derivatives. The aryl azidation followed by an intramolecular C-H amination smoothly proceeded under visible light irradiation without any photocatalyst, demonstrating the synthetic versatility of areneazo-2-(2-nitro)propanes. The in situ generation of aryl azide intermediates was executed under mild visible light photolysis conditions, showcasing the synthetic versatility of areneazo-2-(2-nitro)propanes, a safe alternative of diazonium salts.
