The total synthesis of hemiketal E2 (HKE2) has been accomplished using a gold(I)-mediated cycloisomerization followed by oxidation of the enol ether product to introduce a unique keto-hemiketal, the core structure of HKE2. Synthetic hemiketal E2 reproduced biosynthetically derived HKE2 in the inhibition of human platelet aggregation.
半缩酮 E 2 (HKE 2 ) 的全合成已使用金 (I) 介导的环异构化,然后氧化烯醇醚产物以引入独特的酮基半缩酮,即 HKE 2的核心结构。合成的半缩酮 E 2在抑制人血小板聚集方面再现了生物合成衍生的 HKE 2 。
