DuPhos and BPE Ligands: Highly Efficient Privileged Ligands
(+)-1,2-Bis[(2R,5R)-2,5-diethylphospholano]ethane can be used as a reactant to prepare:
  • Chromium diphosphine chloride complex which is employed as a catalyst for chemoselective oligomerization reaction.
  • α-Arylpyrrolidines by Suzuki-Miyaura cross-coupling and enantioselective copper-catalyzed intramolecular hydroamination reactions.

It can also be used as a catalyst in the enantioselective preparation of (perfluoroalkyl)butenyldiketones via cross Rauhut-Currier reaction of β-perfluoroalkylenones and vinyl ketones.

DuPhos and BPE Ligands

Asymmetric hydrogenation reactions represent the ideal process for the commercial manufacture of single-enantiomer compounds, because of the ease by which these robust procedures can be scaled up and because of the low levels of byproducts generated in these asymmetric hydrogenations.
