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.

萘醌21分四个步骤合成3-deoxyrabelomycin,总收率为17%。通过将
5-甲基环己烷-1,3-二酮共轭添加到21中,然后进行甲基化和碱诱导的环化反应,制得有角度稠合的环系。
