Description

Application

DSM MonoPhos Family of Highly Efficient Privileged Ligands

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
