Descripción

Descripción general

1,2-Bis[(2S,5S)-2,5-diethylphospholano]benzene(1,5-cyclooctadiene)rhodium(I) trifluoromethanesulfonate is an electron-rich C₂ symmetric bis(phospholane) ligand for enantioselective catalytic reactions.[1]

Aplicación

DuPhos and BPE Ligands: Highly Efficient Privileged Ligands

Catalyst involved in:

• Oxidation of the δ-position via ruthenium catalysis
• Stereoselective hydrogenation reactions of dehydroamino acid esters and macrocyclic peptideomimetics
• Synthesis of cyclopeptide alkaloid mucronine E, fluoro-containing amino acids, and labeled protease inhibitors

(S,S)-Et-DUPHOS-Rh may be used as an efficient catalyst in the synthesis of (S)-2-quinolylalanine via asymmetric hydrogenation.[2]
