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
Pyrrolylquinones and indolylquinones useful for treating diseases such as neurodegenerative disease, viral infections and proliferative disease are described, along with methods of making such compounds and pharmaceutical formulations containing such compounds.

A method has been developed to sequentially add indole-3-mercurials to dichlorinated quinones using palladium catalysis. These reactions can be used in the modular assembly of bis(indol-3-yl)benzoquinones, a significant natural product family.
