Five different approaches to the preparation of 6,7-benzo-3,4-(1,4-dimethoxy-2,3-naphtho)-1,5-dioxosuberane (3), an intermediate needed for the synthesis of radermachol (1), the red pigment from the roots of Radermachera xylocarpa, are described. The synthesis of radermachol (1) has been accomplished from 1,4-nephthoquinone in 14 steps.
