method for the synthesis of an indolo[2,3-a]pyrrolo[3,4-c]carbazole ring system is described. The method involves two key processes: a coupling reaction between indole and substituted methylmaleimide portions using lithium hexamethyldisilazide (LiHMDS) as a base, and the oxidativecyclization of bisindolylmaleimide with palladium (II) chloride. We applied this method to the synthesis of arcyriaflavin
