Diphenylalanine is the unnatural amino acid with the formula (C₆H₅)₂CHCH(NH₂)CO₂H. The compound is structurally related to the amino acids alanine and phenylalanine. It has been used for the synthesis of pseudopeptide analogues that are capable of inhibiting certain enzymes.^[1]

Individual enantiomers of this compound can be synthesized via electrophilic amination of a chiral oxazolidinone derivative of 3,3-diphenylpropanoic acid.^[2]

The term diphenylalanine in the context of scientific literature is typically used for the dipeptide of phenylalanine (Phe-Phe [Wikidata]).
