Application

(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.
