A simple and convenient route for synthesis of a series of 4-or 6-substituted indirubin derivatives by oxidation and subsequent condensation of indoxyl and isatin is described. Acidic reaction conditions are crucial to the condensation of 4-substituted derivatives, whereas for the condensation of 6-substituted derivatives, both acidic and basic conditions work well.
