conjugate addition of indoles to 2,5-dichlorobenzoquinone have been developed. A wide variety of indoles substituted with halogen, alkyl, alkoxy, and aryl groups participate in anaerobic condensation reactions promoted by HCl, H2SO4, or CH3CO2H. The hydroquinone product is partially oxidized by excess dichlorobenzoquinone and fully converted to the 2,5-dichloro-3-(indol-3-yl)benzoquinone targets by

with fungi: Bis-indolylquinones are fungal natural products endowed with interesting pharmacological properties. Here a new one-pot mechanochemical methodology for the synthesis of indolylquinones is described, which takes place via domino Michael addition/oxidation processes starting from indoles and dihaloquinones in the presence of FeCl3 or p-TsOH as catalysts and Fetizon's reagent as an oxidant
