A new method has been developed for the synthesis of 2-benzylpyrrolidines utilizing cross-coupling and photoredox catalysis. Using a well-established dual Ni–Ir system, we were able to successfully couple benzylsulfonium salts with proline utilizing radical forming through CO2 extrusion. This enabled the simple one-step synthesis of 2-benzylpyrrolidines from stable, inexpensive starting materials.
