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。
