(±)-3-Deoxyrabelomycin (2) and the linear anthraquinone (3), an intermediate for synthesis of de(methoxycarbonyl)aklavinone (5), have been synthesized by regioselective lithiation of (η6-arene)chromiumtricarbonylcomplexes.

3-deoxyrabelomycin was synthesized from the electron-deficient naphthoquinone 21 in four steps in 17% overall yield. The angularly-fused ring system was made by the conjugate addition of 5-methylcyclohexane-1,3-dione to 21 followed by methylation and base-induced cyclization.
