The total synthesis of calothrixin B and its analogs was achieved starting from 2-methylindole. The synthesis involved an electrocyclization of 2-nitroarylvinyl-3-phenylsulfonylvinylindoles as a key step to give 2-nitroaryl-4-methoxy-3-methylcarbazoles. Oxidation of these compounds followed by reductive cyclization led to N-phenylsulfonylquinocarbazoles. These quinocarbazoles underwent hydrolysis and aerial oxidation in one pot to give the target compounds.
