Indole, as one of the most important nitrogen-containing heterocyclic compound, is found widely in various natural products and synthetic drugs. 3-Iodoindoles play an important role as intermediate in the selective functionalization of indoles. 3-iodoindoles could be conveniently synthesized by electrochemical annulations of o-alkynylanilines with readily available iodide salt. This sustainable electrolysis strategy provides an efficient access to a series of 3-iodoindoles in good to excellent yields under external oxidant-free, base-free conditions and features broad functional group tolerance.

Key words: electrosynthesis, annulation, 3-iodoindoles, o-alkynylanilines
