Catalytic asymmetric hydrogenation has become a key technology in academic research [1] and in industry [2] owing to its generally unrivalled efficiency and selectivity.[3] Nevertheless, no satisfactory solution for the asymmetric hydrogenation of aromatic or heteroaromatic substrates according to Scheme 1 exists,[4] although these compounds are readily available and the reaction has the potential for the simultaneous creation of multiple stereocenters. ...
