Abstract
A new family of bidentate diphosphine ligands which contain a glucofuranoside as a simple but highly effective chiral backbone are reported. These ligands are prepared in a few steps from readily available d-(+)-glucose. These new ligands have been applied to the rhodium-catalysed hydrogenation of α,β–unsaturated carboxylic acid derivatives under very mild reaction conditions, with enantiomeric excesses of up to 98%.
