(+)-1,2-Bis((2S,5S)-2,5-diphenylphospholano)ethane
Chiral Phosphine Ligand
(+)-1,2-Bis((2S,5S)-2,5-diphenylphospholano)ethane is a chiral bisphosphine ligand primarily utilized in asymmetric catalysis. This compound facilitates enantiodivergent synthesis in rhodium-catalyzed reductive hydroformylation of alkenyl boronic esters, leading to the production of chiral γ-boryl alcohols. Additionally, it forms chiral nickel-phosphine complexes that promote asymmetric hydrogenation of aliphatic γ- and δ-keto acids, enhancing both substrate activation and selectivity through hydrogen bonding interactions.
