Аннотация: Electrocatalytic transformation of aldehydes, 2,4-dihydro-3H-pyrazol-3-ones and kojic acid in alcohols occurs in an undivided cell in the presence of sodium halides, selectively affording substituted 4-{[3-hydroxy-6-(hydroxymethyl)-4-oxo-4H-pyran-2-yl](aryl)methyl}-5-methyl-1,2-dihydro-3Hpyrazol-3-ones in 73–95% yields and with 240–320% current efficiency. The multicomponent process provides a facile and efficient way to the new type of systems with heterocyclic moieties separated by aryl-substituted C-spacer. The product structure has been confirmed by X-ray diffraction data

Ключевые слова: electrocatalysis, multicomponent process, tandem reaction, aldehydes, 2,4-dihydro-3H-pyrazol-3-one, kojic acid.
