An improved process for preparing adrenaline, or an addition salt thereof, on an industrial scale, with asymmetric hydrogenation as a key step and a special sequence of successive steps, using [Rh(COD)Cl]2 as catalyst and a chiral, bidentate phosphine ligand such as (2R,4R)-4-(dicyclohexylphosphino)-2-(diphenylphosphinomethyl)-N-methylaminocarbonylpyrrolidine as the catalyst system. |
