(R)-SEGPHOS Chemical Properties,Usage,Production

  • Reactions
    1. Biaryl bisphosphine ligand with narrow dihedral angle. The SEGPHOS® ligand has been applied to a variety of metal catalyzed reactions. In many cases, yields and enantioselectivities, exceed results obtained earlier using BINAP.
    2. As ruthenium complex, SEGPHOS® generally gives higher levels of chiral induction in asymmetric hydrogenations of α,β,and γ-functionalized ketones. 
    3. Used in Rh-catalyzed transformations such as: (a) 1,4-addition of boronic acids to coumarins, (b) addition of titanium reagents to imines,(c) cotrimerization of alkenes and acetylenes,10 (d)double [2+2+2] cycloaddition,11 (e) indanone formation.
    4. Used in Pd-catalyzed transformations such as: (a) cycloaddition of 1,6-enyne,(b) arylative cyclization of allenyl aldehydes with boronic acids,13 (c) synthesis of chromans.
    5. Used in Cu-catalyzed transformations such as: (a) nitroso Diels-Alder,(b) reductive aldol condensation,(c) conjugate reduction of unsaturated sulfones,and phophonates.
    6. Iridium-catalyzed asymmetric hydrogenation of quinolines activated by chloroformates.
    7. Iridium-catalyzed asymmetric transfer hydrogenation used in polyketide construction.
    8. Rhodium-catalyzed asymmetric hydroarylation of 3-pyrrolines.
    9. Palladium-catalyzed regio- and enantioselective dearomatization.
