The mechanism can be found in the book Named Reactions in Organic Chemistry , [1] and its more intuitive version is provided below: Marschalk Reaction. Sodium dithionite reduction of 1-hydroxy- or aminoanthraquinones to their leuco-forms, followed by condensation with aldehydes to yield the 2-alkylated anthraquinones.

Two compounds, the 4H-anthra[1,2-b]pyran 1 and the anthraquinone derivative 6 were evaluated for Die Marschalk-Reaktion kann auch zweimal an einem Molekül durchgeführt werden, sodass zwei verschiedene Seitenketten hinzugefügt werden. Dafür müssen die Seitenketten jedoch in richtiger Reihenfolge hinzugefügt werden, da unter normalen Reaktionsbedingungen kein höherer aliphatischer oder aromatischer Aldehyd als zweite vicinale Alkylgruppe mehr eingeführt werden kann.

We describe herein a simple and efficient method to derivatize 1,4‐dihydroxyanthraquinone by using a modified Marschalk reaction. Hai Shan Jin, Li Ming Zhao, A contribution to the study of the modified Marschalk reaction: Hydroxymethylation of 6,8-O-dimethyl emodin, Chinese Chemical Letters, Abstract. Anthracyclinones of the rhodomycinone type (type A) can efficiently be synthesized by Marschalk reaction of hydroxy aldehydes 1.Both diastereoisomeric cyclization products 2 and 3 are obtained in aqueous-methanolic reaction medium but the natural configuration 2 is formed almost exclusively under phase transfer conditions.
