  A General Approach to Angucyclines: Synthesis of Hatomarubigin A, Rubiginone B2, Antibiotic X-1488E, 6-Hydroxytetrangulol, and Tetrangulol

  摘要：

  Hatomarubigin A was prepared in 41% yield in a single procedure from acyl naphthoquinone 15 and 5-methylcyclohexane-1,3-dione (16). The net reaction consists of Michael addition to an acyl quinone followed by intramolecular aldol condensation. Hatomarubigin A then served as a common intermediate in syntheses of the angucyclinone antibiotics rubiginone B2, antibiotic X-1488E, 6-hydroxy-tetrangulol, and tetrangulol.

  in 6–7 steps from the common precursor 18b. The key naphthalenones 6 were prepared in 5 steps from tetralone 17 in a regioselective manner. Anionic annulation of cyanophthalide 7c with 6 readily provided tetracyclic precursors 5 in excellent yields, sunlight-promoted photooxidation of which led to the synthesis of the title compounds.

• Synthesis Study toward Mayamycin

  Natural product mayamycin is the first example in the angucycline class featuring a C‐glycoside linkage at the C5‐position of the benz[a]anthracenone core with remarkable biological activities. We successfully synthesized the two retrosynthetic fragments, but found that the final C‐glycosylation did not occur. Alternatively, an A‐ring saturated aglycon was prepared, but the proposed C‐glycosylation

  天然产物玛雅霉素是安古霉素类中的第一个例子，在苯并[ a ]蒽环酮核心的C5位具有C-糖苷键，具有显着的生物活性。我们成功合成了两个逆合成片段，但发现最终的C糖基化没有发生。另外，还可以准备一个A环饱和糖苷配基，但建议的C-糖基化反应仍未进行。最后，使用简化的底物，随后的C糖基化顺利进行，从而减少了两环的玛雅霉素类似物。
