Abstract
A novel chiral phosphite–phosphoramidite ligand based on 2-anilinoethanol and R-BINOL moieties has been synthesized in one-pot. The ligand was evaluated in the rhodium-catalyzed enantioselective hydrogenation of α- and β-dehydroamino acid derivatives and dimethyl itaconate in three different solvents at 25 °C, at 1 or 50 bar of hydrogen pressure. The solvent and the pressure effect are discussed.
