摘要：

High and wide: The high rigidity and large dihedral angle of chiral, spirobifluorene-based diphosphane ligands lead to excellent reactivity and enantioselectivity in the ruthenium-catalyzed asymmetric hydrogenation of α,β-unsaturated carboxylic acids (see scheme). © 2005 Wiley-VCH Verlag GmbH & Co.
