2-Acyl-N-propargylindoles 1 and 2-acyl-3-propargylindoles 5 undergo aminobenzannulationreactions with pyrrolidine in the presence of an appropriate Lewisacid to give 9-aminopyrido[1,2-a]indoles 6 and 1-aminocarbazoles 7, respectively. The selection of the appropriate Lewisacid, TiCl4 or GaCl3 for 1 and InCl3 for 5, allows the domino process involving the initial formation of an enamine intermediate
