(+)-1,2-Bis((2S,5S)-2,5-diphenylphospholano)ethane

Overview

(+)-1,2-Bis ((2S,5S)-2,5-diphenylphospholano)ethane ((S,S)-Ph-BPE) is a chiral bisphosphine ligand and catalyst. (+)-1,2-Bis ((2S,5S)-2,5-diphenylphospholano)ethane acts as a chiral ligand in rhodium-catalyzed reductive hydroformylation of alkenyl boronic esters, enabling enantiodivergent synthesis of chiral γ-boryl alcohols. (+)-1,2-Bis ((2S,5S)-2,5-diphenylphospholano)ethane forms chiral nickel-phosphine complexes to mediate asymmetric hydrogenation of aliphatic γ- and δ-keto acids; protons promote substrate C = O bond activation and stereoselectivity control via hydrogen bonding. (+)-1,2-Bis ((2S,5S)-2,5-diphenylphospholano)ethane forms a monodentate nickel complex, which serves as the active species for asymmetric hydrogenation of aliphatic keto acids.
