Abstract

Chiral phosphoric acids (CPA) have become a privileged catalyst type in organocatalysis, but the selection of the optimum catalyst is still challenging. So far hidden competing reaction pathways may limit the maximum stereoselectivities and the potential of prediction models. In CPA catalyzed transfer hydrogenation of imines, we identified for many systems two reaction pathways with inverse ...
