Abstract
γ-Hydroxycarboxylic esters and γ-lactones which are suitable as flavors can be prepared by electrochemical reductive cross-coupling of α,β-unsaturated esters with carbonyl compounds in an undivided electrolysis cell having a cathode composed of lead, lead alloys, cadmium, cadmium alloys, mercury, steel, glassy carbon or boron-doped diamonds and a basic aqueous electrolyte comprising an electrolyte salt which suppresses the cathodic formation of hydrogen.
