Electrochemically induced multicomponent ‘one-pot’ assembling benzaldehydes, N,N′-dimethylbarbituric acid, and kojic acid

The new electrochemically induced multicomponent assembling was found: the electrocatalytic transformation of benzaldehydes, N,N′-dimethylbarbituric acid, and kojic acid has been carried out in alcohols in an undivided cell in the presence of sodium halides with the selective formation of the earlier unknown substituted 5-[[3-hydroxy-6-(hydroxymethyl)-4-oxo-4H-pyran-2-yl](phenyl)methyl]-1,3-dimethylpyrimidine-2,4,6(1H,3H,5H)-triones in 65–88% yields and with 325–440% current efficiency. This new multicomponent process provides facile and efficient way to the novel type of separated by C-aryl-substituted spacer both 4-oxo-4H-pyran and 1,3-dimethylpyrimidine-2,4,6(1H,3H,5H)-trione pharmacology active systems, which are promising compounds for different biomedical applications.
