摘要：

With a little help from my friend: Combination of the racemic binap ligand with enantiopure bis-(S)-binol-borate anion results in enantioselectivities up to 57% ee in the rhodium-catalyzed asymmetric hydrogenation of dimethyl itaconate, which corresponds to 85% of the asymmetric induction caused by the enantiopure binap ligand. © 2010 WILEY-VCH Verlag GmbH & Co.
