Abstract
A metal-free divergent synthesis of indole compounds dependent on a reagent via intramolecular C(sp2)-H amination was described. The reaction of 2-vinylanilines with DMSO/SOCl2 at 70 °C was found to give 2-thiomethylindoles, while replacing DMSO with diethyl sulfoxide afforded 2-unsubstituted indoles in a highly selective manner.
