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.

Features and Benefits

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

[formula: see text] The zinc enolates, resulting from the copper-catalyzed enantioselective conjugate addition of dialkyl zinc reagents to cyclic and acyclic enones, could be trapped, quantitatively, as silyl enol ethers with TMSOTf in apolar solvents or with TMSCI and NEt3.

[reaction: see text] The enantioselective catalytic 1,4-addition to alpha,beta-unsaturated ketimines is an unprecedented process. Herein, we document the copper-catalyzed addition of dialkylzinc reagents to (2-pyridylsulfonyl)imines of chalcones. This process occurs rapidly in the presence of a chiral phosphoramidite ligand to
