Sažetak

Electrochemical synthesis of amino acids by reduction of
phenylhydrazones of the folowing a-ketoacids: pyruvic, a-ketovaleric,
a-ketoglutaric and a-ketooctane acid was studied. The
corresponding a-amino acids were obtained in 44--55~/o yield using
controlled potential electrolysis on mercury pool electrode in 0.5 M
HCl aqueous ethanol solution.
A mechanism rationalizing the reduction products of the phenylhydrazone
of pyruvic acid as well as polarographic and coulometric
data are proposed.
