tert -Butanesulfinylphosphines: Simple Chiral Ligands in Rhodium-Catalyzed Asymmetric Addition of Arylboronic Acids to Electron-Deficient Olefins

ADVANCED SYNTHESIS & CATALYSIS (PREVIOUSLY: JOURNAL FUER PRAKTISCHE CHEMIE), Issue 5 2010
Feng Lang
Abstract An efficient rhodium complex catalyst system was developed by using a class of simple tert -butanesulfinylphosphines as bidentate ligands, which solely bear sulfur chirality and combine the advantages of both sulfoxide and phosphine ligands. Excellent activities (in 0.5 hour, up to 99% yield) and enantioselectivities (up to 98% ee) were displayed in Rh-catalyzed asymmetric 1,4-additions under mild conditions. [source]

An N -Linked Bidentate Phosphoramidite Ligand (N- Me-BIPAM) for Rhodium-Catalyzed Asymmetric Addition of Arylboronic Acids to N- Sulfonylarylaldimines

Abstract A chiral N -linked C2 -symmetric bidentate phosphoramidite (N- Me-BIPAM) was newly developed for the rhodium-catalyzed enantioselective addition of arylboronic acids to N- sulfonylimines. This ligand achieved high enantioselectivities in a range of 84,99% ee in additions of arylboronic acids to N- tosyl- and N- nosylarylaldimines. [source]
