method for regio- and chemoselective Friedel–Crafts acylation of indole using acyl chlorides in the presence of ZrCl4 has been discovered. It minimizes/eliminates common competing reactions that occur due to high and multiatom-nucleophilic character of indole. In this method, a wide range of aroyl, heteroaroyl alkenoyl, and alkanoyl chlorides undergo smooth acylation with various indoles without NH
