摘要

The commercially available ferrocene-based diphosphine ligand (S-c,S-Fc)-TaniaPhos was found to be highly effective in the Rh-catalyzed asymmetric hydrogenation of 3-aryl-2-(phosphonomethyl)propenates. Excellent enantioselectivity (90-98% ee) and high catalytic activity (S/C up to 1000) have been achieved, which represents the best results reported so far. (C) 2011 Elsevier Ltd.
