The new synthetic method of indolizino[3,4,5-ab]isoindoles (INIs) by an acid-induced intramolecular cyclization of 1,2-di(1H-pyrrol-2-yl)benzenes has been developed. This protocol can be applied to the preparation of INI derivatives with electron-donating and -withdrawing groups as well as azaINIs. (C) 2015 Elsevier Ltd. All rights reserved.
