(S)-(-)-5,5'-Bis(diphenylphosphino)-4,4'-bi-1,3-benzodioxole,min.98%(S)-SEGPHOS Chemical Properties,Uses,Production

Reaction

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. See ruthenium complexes 44-0096, 44-0518, 44-0168.
Used in Rh-catalyzed transformations such as: (a) 1,4-addition of boronic acids to coumarins,4 (b) addition of titanium reagents to imines, (c) cotrimerization of alkenes and acetylenes, (d) double [2+2+2] cycloaddition,11 (e) indanone formation.12a,b
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,15 and phophonates.
Iridium-catalyzed asymmetric hydrogenation of quinolines activated by chloroformates.

Uses

(S)-(-)-SEGPHOS? is a chelating ligand used to prepare coordination complex catalysts, such as its use in Pd catalysts for the enantioselective synthesis of spiro- or benzofused hetereocycles with exocyclic olefins via enantioselective intramolecular dearomative Heck reaction of indoles, benzofurans, pyrroles and furans.
