| (S)-(R)-JOSIPHOS Usage And Synthesis |
| Reactions |
- Ferrocenylphosphine ligands of the type cpFecp(PR2)(*CH(CH3)PR'2) are a class of asymmetric ligands developed at Solvias in Basel, Switzerland. Ligands of this type are currently used industrially in the stereoselective synthesis of commercial products. A unique feature of these bidentate ligands is the presence of a fixed phosphine moiety and a stereogenic,functionalized side chain, which can be easily modified to accommodate electronic and steric requirements. Based on a versatile synthetic procedure starting with optically active ferrocenes of the type cpFecp(PR2)(*CH(CH3)X) [X = OAc or NR2], a variety of donor atoms can be introduced into the side chain.4 These ferrocene based phosphine ligands have wide application in the stereoselective hydrogenation of substituted acetamidoacrylates, enol acetates, β-ketoesters and simple alkenes.
- Pd-catalyzed, enantioselective, intramolecular α-substituted cyclic ketones: facile synthesis of functionalized chiral spirobicycles.
- Asymmetric boron conjugate addition of α,β-unsaturated carbonyl compounds catalyzed by
- CuOTf/Josiphos under non-alkaline conditions.
- Chiral amides via copper-catalyzed enantioselective conjugate addition.
- Ruthenium-catalyzed enantioselective synthesis of β-amino alcohols from 1,2-diols by “borrowing hydrogen”.
- Cobalt-catalyzed asymmetric addition of silylacetylenes to 1,1-disubstituted allenes.
