| Abstract
| - An X-ray diffraction experiment revealed an interestingtriphosphorous bidentate coordination in a Pd(II) complexof a phosphine-phosphoramidite ligand 1, which showedexcellent enantioselectivity (up to 99.4% ee) in Rh-catalyzedhydrogenation of α-dehydroamino esters in acetone. Adramatic solvent effect was found in the hydrogenation ofitaconates, which induces opposite chiralities of the productwith the same catalytic system by the use of different solvents(e.g., 99.6% ee (R) in TFE vs 71.2% ee (S) in methyl ethylketone).
