摘要：
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 enantio selective hydrogenation of alpha- and beta-dehydroamino acid derivatives and dimethyl itaconate in three different solvents at 25 degrees C, at 1 or 50 bar of hydrogen pressure. The solvent and the pressure effect are discussed. (C) 2007 Elsevier Ltd. All rights reserved.
