Application

Use of 5,5-(Dimethyl)-i-Pr-PHOX as a Practical Equivalent to t-Bu-PHOX in Asymmetric Catalysis

Design, Synthesis, and Applications of Potential Substitutes of t-Bu-Phosphinooxazoline in Pd-Catalyzed Asymmetric Transformations and Their Use for the Improvement of the Enantioselectivity in the Pd-Catalyzed Allylation Reaction of Fluorinated Allyl Enol Carbonates
(S)-5,5-(Dimethyl)-i-Pr-PHOX is a phosphinooxazoline ligand (PHOX), belongs to the class of non-C2 symmetric chiral ligand.
It can be used in:
  • The enantioselective Pd-catalyzed allylation reactions.
  • The synthesis of (R)-2-phenyl-2,5-dihydrofuran by the enantioselective Heck reaction between 2,3-dihydrofuran and phenyl triflate.
  • The allylation reaction of fluorinated allyl enol carbonates and fluorinated silyl enol ethers to prepare allylated tert α-fluoroketones.

Andreas Pfaltz has a longstanding interest in the design of chiral ligands for asymmetric catalysis. The semicorrins developed in his group served as the prototype for an important family of nitrogen ligands, the bisoxazolines, which have found widespread use in catalytic asymmetric synthesis.

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