Application

Diphenylacetic acid can be used as a reagent in the kinetic resolution of racemic 2-hydroxy-γ-butyrolactones and 1-heteroarylalkanols by asymmetric esterification in the presence of pivalic anhydride and chiral acyl-transfer catalyst.
It can also be used as:
  • An additive in the ortho-arylation of 1-phenyl-β-carbolines using various aryl halides in the presence of ruthenium catalyst.
  • A catalyst to synthesize 2-allyl-3-oxazolin-5-one derivatives via Rh-catalyzed coupling reaction of azlactones and alkynes followed by aza-Cope rearrangement.

A Ru(II)-catalyzed C-H arylation approach has been developed utilizing β-carboline alkaloids as the directing group. Selective formations of diarylated products from moderate to excellent yields were accomplished. Broad substrate scope with excellent functional group tolerance for C1-phenyl/thienyl/PAHs-β-carbolines was demonstrated. X-ray
