Synthesis of indoles via electron-catalyzed intramolecular C?N bond formation
A new protocol for the preparation of N-substituted indole-3-carboxylates has been developed. The key C?N bond formation occurs under transition-metal-free conditions employing a t-BuOK/DMF system without special initiators or additives. Across a number o

N-cyclopropylation of indoles and cyclic amides with copper(II) reagent
Copper-mediated coupling reactions of cyclopropylboronic acid with indoles and cyclic amides are described. The process utilizes catalytic or stoichiometric amounts of copper(ll) acetate, DMAP, and NaHMDS at 95 °C under an atmosphere containing oxygen. A variety of functional groups remain intact throughout the reaction.
