and therefore is expected to be a lead compound for obesity drugs. To establish its absolute configuration, and to provide sufficient amounts for further research, the total synthesis of yoshinone A was achieved through synthesis of its two possible diastereomers.
2014 年,从海洋蓝藻 Leptolyngbya sp. 中分离出含有 γ-吡喃酮的聚酮化合物 yoshinone A。并确定了其结构。Yoshinone A 抑制 3T3-L1 细胞向脂肪细胞的分化,EC50 值为 420 nM,没有任何细胞毒性,因此有望成为肥胖药物的先导化合物。为了确定其绝对构型,并为进一步研究提供足够的数量,yoshinone A 的全合成是通过合成其两种可能的非对映异构体来实现的。
