oxidative coupling of indoles and phenols to benzofuroindoline-containing polycyclic scaffolds related to the naturalproduct bipleiophylline. Suitable conditions from N-substituted indoles are developed and applied to the synthesis of a hexacyclic model starting from a tetracyclic ABCE precursor. We report our efforts to apply an N-iodosuccinimide-mediated dearomative oxidative coupling of indoles

Palladium-catalyzed heteroannulation between indole-3-butanal and various o-iodoanilines provides a straightforward synthesis of 1,2-bis(3-indolyl)ethanes, which are useful precursors to valued indolo[2,3a]carbazoles. 1,2-Bis(3-indolyl)ethanes bearing a variety of substituents are available by using this methodology, with one transformed into the natural product 1,2-bis(3-indolyl)ethane-1,2-dione through a novel double Yonemitsu oxidation.
