2-Propynamides have been never used as substrates in classic and TfO-promoted Bischler-Napieralski reactions. In this article, a novel tandem synthesis of benzo[]acridines is developed from -aryl-2-propynamides and alkynes consisting of a TfO-promoted intermolecular Bischler-Napieralski reaction and a TfOH-promoted intramolecular Friedel-Crafts reaction.
