A new and convergent synthesis of ascididemin is presented. Using an anionic cascade ring closure as the key step, this natural product is obtained in 45% overall yield in just 6 steps starting from 2′-fluoroacetophenone. This new approach was extended to the synthesis of a new isomer of ascididemin.
提出了一种新的海鞘胺的聚合合成方法。以阴离子级联闭环为关键步骤,以
2'-氟苯乙酮为原料,仅用 6 个步骤即可获得该
天然产物,总产率为 45%。这种新方法被扩展到海鞘胺新异构体的合成。
