General description

Optical rotation devation ± 13

Application

DuPhos and BPE Ligands: Highly Efficient Privileged Ligands
(R,R)-i-Pr-DUPHOS is a chiral phospholane class of ligand that can be used in:
  • The catalytic asymmetric hydrogenation reactions.
  • Rhodium catalyzed enantioselective synthesis of 1,2 diols via asymmetric intramolecular hydrosilylation of α- and β-hydroxyketones.
  • In the enantioselective synthesis of diarylmethanols by arylation of aromatic aldehydes with arylboronic acids in the presence of a rhodium catalyst.
