Marschalk reaction

The Marschalk reaction is the sodium dithionite promoted reaction of a phenolic anthraquinone with an aldehyde to yield a substituted phenolic anthraquinone after the addition of acid. The mechanism can be found in the book Named Reactions in Organic Chemistry, and its more intuitive version is provided below: One of the first applications of this reaction was reported in 1985.
