Application

Chiral phosphoramidite ligand used in a highly enantioselective copper-catalyzed conjugate addition of diakylzincs to a variety of Michael acceptors. Also used in a palladium-catalyzed diethylzinc mediated umpolung allylation.
The product may be used as a ligand in:
  • Iridium-catalyzed allylic etherification of acyclic, achiral allylic carbonates with potassium silanolates to form chiral allylic alcohols.
  • Palladium-catalyzed asymmetric allylic cyclisation of N-tosyl and N-benzyl carbonates to form the corresponding pyrrolidine and piperidine derivatives, respectively.
  • Intramolecular iridium-catalyzed allylic cyclizationof (E)-allylic methyl carbonates to form 2,5-trans/cis pyrrolidine derivatives.

Features and Benefits

Advantages of the MonoPhos® ligands:
  • Superior enantiocontrol in numerous transformations
  • High activities at low catalyst loadings
  • Hydrogenations under low-pressure conditions
