electrolysis of isatins and cyclic1,3-ketoesters in acetone in an undivived cell results in the formation of the previously unknown 3-substituted-3-hydroxyindol-2-ones in 80–95% yields and 800–950% current efficiency. Thus, this simple electrocatalytic system can produce in aprotic solvent in an undivided cell, under mild conditions the new electrochemicallyinducedaldol reaction of isatins and cyclic 1,3-ketoesters
