摘要：

Goodwin-Lions-type sp2N/sp3N hybrid ligands R-BINAN-R′-Py possessing a C2 axis binaphthyl skeleton have been designed and synthesized. Combination of the new non-phosphine ligand with Ru(π-CH2C(CH3)CH2)2(cod) has been revealed to catalyze the hydrogenation of aromatic ketones with high enantioselectivity of up to 99% ee. The reaction proceeds essentially without the need for any bases, but the reactivity is enhanced by the addition of KOt-C4H9 attaining an S/C ratio of up to 10000. The success should expand the range of possibilities in designing catalysts not only for hydrogenation but also for many other reactions. Copyright © 2006 American Chemical Society.
