Substituted γ-benzyl-L-glutamates and β-benzyl-L-aspartates have been obtained from the alkali metal salts of the corresponding amino acid copper complexes and substituted benzyl halides under various experimental conditions. The use of a sequestering agent to remove the copper from the intermediate ester complexes allows the introduction of relatively sensitive ester groups. Several other types of ester were also prepared in the same way.
