preparation of indoles has been developed. This process is based on sterically congested hypervalent iodine compounds of the family of Koserreagents, and iodosobenzene in combination with 2,4,5‐tris‐isopropylbenzene sulfonic acid provides the highest yields and fastest reaction times. This reagent alone promotes the chemoselective oxidative cyclization of 2‐amino styrenes to indoles in high yields
