| Technical Notes: 1. Biaryl bisphos phine ligand with narrow dihedral angle. The DM-SEGPHOS ligand, as the ruthenium complex, gives superior enantios electivity and diastereoselectivity in the asymmetric hydrogenation of a-substituted-ß-ketoesters. See 15-0066. 2.Copper catalyzed enantioselective [3 + 2] cycloaddition as a route to Y amino ketones and 3-pyrrolidinones. 3.Palladium catalyzed e nantioselective addition of malonates to dihydroisoquinolines. 4.Ruthenium catalyzod enantioselective synthesis of ß amino acids by hydroge nation 5.Ruthenium catalyzed asymmetric hydrogenation of 3-quinuclidinone. See 44-0098 for Ru catalyst. 6.Diastereo- and enantioselective ruthenium- catalyzed hydrohydroxyalkylation of 2-silyl-butadienes. 7.Asymmetric [2 +2+2] cycloaddition. 8.Linear selective C-H activation. 9. Ligand used in the asymmetric hydrogenation of quinoxalines, benzoxazines and Benzothiazine . |
