Asymmetric Hydrogenation of Quinoxalines Catalyzed by Iridium/PipPhos

A catalyst made in situ from the (cyclooctadiene)iridium chloride dimer, [Ir(COD)Cl]2, and the monodentate phosphoramidite ligand (S)‐PipPhos was used in the enantioselective hydrogenation of 2‐ and 2,6‐substituted quinoxalines. In the presence of piperidine hydrochloride as additive full conversion...
