An efficient large-scale preparative synthesis of biologically interesting β,β,β-trifluoroalanine through the biomimetic transamination of the ethyl trifluoropyruvate has been developed. The azomethine—azomethine isomerization of the N-(1-phenyl)ethylimine of ethyl trifluoropyruvate to the N-(1-phenyl)ethylidene alanine ethyl ester, a key stage of the process, was found to occur under the mild reaction
