(R)-SEGPHOS Chemical Properties,Uses,Production
Reactions
- 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.
- As ruthenium complex, SEGPHOS® generally gives higher levels of chiral induction in asymmetric hydrogenations of α,β,and γ-functionalized ketones.
- 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.
- 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.
- Used in Cu-catalyzed transformations such as: (a) nitroso Diels-Alder,(b) reductive aldol condensation,(c) conjugate reduction of unsaturated sulfones,and phophonates.
- Iridium-catalyzed asymmetric hydrogenation of quinolines activated by chloroformates.
- Iridium-catalyzed asymmetric transfer hydrogenation used in polyketide construction.
- Rhodium-catalyzed asymmetric hydroarylation of 3-pyrrolines.
- Palladium-catalyzed regio- and enantioselective dearomatization.
Uses
(R)-(+)-SEGPHOS? is a chelating ligand used to prepare coordination complex catalysts, such as its use in Pd catalysts for the enantioselective addition of diesters to 3,3-difluoropropenes, and in the Ni-based catalyst for the asymmetric propargylic amination of propargylic carbonates with an internal alkyne group.
