4-Substitutedindoles containing a variety of electrophiles and N-substituents undergo Friedel−Crafts acylation to give exclusively the products of cyclization at the 5-position of indole. These indanones and tetralones have been scarcely prepared and are subunits in natural products and analogues of potential biological significance.
