    • Recently, Faller et al. reported the resolution of diastereopure (S)- 1a-Rh/ 7 by recrystallization from the diastereomeric mixture ((S)- 1a-Rh/ 7: (R)- 1a-Rh/ 7 = 3: 1) after the kinetic chirality control. The structure was proved by X-ray analysis:

    • Asymmetric catalysts are prepared by a suitable combination of chiral ligands and metals. The asymmetric catalysts thus prepared can be further evolved into more activated catalysts with higher catalytic activity and enantioselectivity by ligation of chiral activators ("Asymmetric Activation", see ref. 18). However, the additional ligation does not necessarily lead to higher catalytic activity, for which we have proposed the term "asymmetric synergy (effect)" leading to higher enantioselectivity without an increase in the catalytic activity (even with a decrease)
