Application

Carreira DOLEFIN Ligands
(1R, 4R, 8R) Carreira DOLEFIN Ligand is a chiral diene ligand that can be used in:
  • The asymmetric Rh-catalyzed arylation of alkenylheterocycles by conjugate additions with various aryl boronic acids.
  • The enantioselective synthesis of 3,3-diarylpropanals by conjugate addition of aromatic boronic acids to cinnamaldehyde derivatives in the presence of a rhodium catalyst.
  • The asymmetric synthesis of pyrrolizidinones by rhodium-catalyzed 1,4-addition of aryl boronic acids to pyrrolidine acceptor.
