<div> <p>We report an efficient and environmentally friendly electrochemical approach to perform the bromo cyclization of tryptophol, tryptamine and tryptophan derivatives. The 3a-bromofuranoindolines and 3a-bromopyrroloindolines obtained are of interest in the total synthesis of natural products. This dearomative procedure relies on the generation of an electrophilic bromine reagent by the electrochemical oxidation of MgBr<sub>2</sub>. No organic byproducts are generated with this protocol which avoids the use of an additional electrolyte.</p> </div>

<div> <p>We report an efficient and environmentally friendly electrochemical approach to perform dearomatization reactions of indoles at a constant potential in an undivided cell at room temperature. MgBr<sub>2</sub> is used as a redox mediator to indirectly oxidize the indole nucleus into a bromonium ion which is involved in dihydroxylation, hydroxycyclization and bromocyclization of indoles. Notably, we synthesized bromopyrroloindolines which are intermediates for the total synthesis of natural products. No organic byproducts are generated with this protocol which avoids the use of an additional electrolyte.<br></p> </div>
