Description
- General description: The product is a phosphinooxazoline (PHOX) ligand introduced by Pfaltz and coworkers. These non-symmetrical modular P,N-ligands are particularly useful in cases where double bond migration leads to undesired products or mixtures of isomers.[1]
- Application: (S)-4-tert-Butyl-2-[2-(diphenylphosphino)phenyl]-2-oxazoline can be used as a ligand for enantioselective Heck reaction without any C=C double bond migration byproduct. It can also be used in a rhodium(I)-catalyzed enantioselective desymmetrization reaction of meso-3,5-dimethyl glutaric anhydride, to form substituted syn-deoxypolypropionate fragments in a single transformation.[1]
