Abstrakt: The electrocatalytic hydrogenatoin of benzylideneazlactone and 5-benzylidenehydantoin with Raney-nickel cathode proceeded smoothly to afford N-acetylphenylalanine and 5-benzylhydantoin, respectively. In addition, refluxing the electrolyte solution after the electrolysis finally yielded phenylalanine with satisfactory chemical yields and current efficiencies. This electrocatalytic process showed slightly higher reactivity than the ordinary catalytic hydrogenation.
