(R)-(+)-5,5'-Bis[di(3,5-xylyl)phosphino]-4,4'-bi-1,3-benzodioxole,min.98%(R)-DM-SEGPHOS Chemical Properties,Usage,Production

Reaction

Biaryl bisphosphine ligand with narrow dihedral angle. The DM-SEGPHOS ligand, as the ruthenium complex, gives superior enantioselectivity and diastereoselectivity in the asymmetric hydrogenation of α-substituted-β-ketoesters.
Copper catalyzed enantioselective [3 + 2] cycloaddition as a route to γ–amino ketones and 3-pyrrolidinones.
Palladium catalyzed enantioselective addition of malonates to dihydroisoquinolines.
Ruthenium catalyzed enantioselective synthesis of β amino acids by hydrogenation.
Ruthenium catalyzed asymmetric hydrogenation of 3-quinuclidinone. See 44-0098 for Ru catalyst.
Diastereoand enantioselective ruthenium-catalyzed hydrohydroxyalkylation of 2-silyl-butadienes.
Asymmetric [2+2+2] cycloaddition.
Linear selective C-H activation.
