%X New syntheses of the naphthalenoid natural products dianellidin [1- (1,8-dihydroxy-3-methylnaphthalen-2-yl) ethanone ] (2) and stypandrone [6-acetyl-5-hydroxy-7-methylnaphthalenel-1,4-dione] (20), which rely on the Fries rearrangement, are described. This methodology is then applied to the synthesis of stypandrol [1,1&#8242;-(1,1&#8242;,8,8&#8242;-tetrahydroxy- 6,6&#8242;-dimethyl-2,2&#8242;-binaphthalene-7,7&#8242;-diyl) bisethanone ] (1), a toxic naphthalenetetrol isolated from Stypandra imbricata R.Br. ('blind grass').
