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

DSM MonoPhos Family

A diverse array of these chiral, monodentate phosphoramidites based on the privileged BINOL platform. The MonoPhos™ family has exhibited high levels of enantiocontrol in synthetic transformations ranging from metal-catalyzed asymmetric 1,4-additions of organometallic reagents to allylic alkylations to desymmetrization of meso-cycloalkene oxides.

DSM MonoPhos™ Ligands

In collaboration with DSM, we are pleased to offer a range of MonoPhos™ ligands for the research market.† Feringa and co-workers have invented a diverse array of these chiral, monodentate phosphoramidites based on the privileged BINOL platform.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
