Pirrung, Michael C.,Park, Kaapjoo,Li, Zhitao

, p. 365 - 367 (2001)

(Matrix Presented) 3-Indolylquinones can be efficiently prepared by the acid-catalyzed condensation of indoles with 2,5-dichlorobenzoquinone, followed by DDQ oxidation. The resulting dichloroquinones are hydrolyzed to the 3-indolyldihydroxybenzoquinones.
