Marschalk reaction

A similar reaction sequence converted -18 to -1 thus proving natural Die Marschalk-Reaktion ist eine Namensreaktion der organischen Chemie, die 1936 von Charles Henri Marschalk (1885–1968) entdeckt wurde. Es handelt sich um die Reaktion eines phenolischen Anthrachinons zu einem substituierten phenolischen Anthrachinon. We describe herein a simple method for the derivatization of 1,4‐dihydroxyanthraquinone through a modified Marschalk reaction.
