Abstract
A novel and efficient synthesis of 2,5-diamino-1,4-benzoquinone is described. The reaction involves a palladium/charcoal hydrogenolysis as the key step and provides the desired product in only four steps and very good overall yield.
Key words
palladium-on-charcoal - hydrogenolysis - 2,5-diamino-3,6-dibromoquinone - terreusinone
