  • An eight-step synthesis of epicolactone reveals its biosynthetic origin
    作者:Pascal Ellerbrock、Nicolas Armanino、Marina K. Ilg、Robert Webster、Dirk Trauner
    DOI:10.1038/nchem.2336
    日期:2015.11
    structure, it poses a considerable challenge to synthesis, a challenge that can be met by understanding its biosynthetic origin. If drawn in a certain way, epicolactone reveals a pattern that resembles purpurogallin, the archetype of ubiquitous natural colourants formed via oxidative dimerization. Based on this insight, we designed a biomimetic synthesis of epicolactone that proceeds in only eight steps
    Epicolactone是一种最近分离出的真菌代谢产物,其大小非常复杂,但具有外消旋性。凭借其四级立体中心阵列,高度的功能化和复杂的多环结构,它对合成提出了相当大的挑战,这一挑战可以通过了解其生物合成来源来解决。如果以某种方式绘制,Epicolactone会显示出一种与紫杉醇相似的图案,紫杉醇是通过氧化二聚作用形成的普遍存在的天然着色剂的原型。基于这一见解,我们设计了仿生的环氧乙烷内酯的合成过程,该过程仅从香草醇中进行了八步。我们已经分离出了支持我们生物合成假说的关键中间体,并预计也可以发现源自我们合成努力的表内酯的异构体也可以作为天然产物。

  • An Interesting Issue of Diels−Alder Selectivity Discovered En Route to 11-<i>O</i>-Debenzoyltashironin
    作者:Silas P. Cook、Samuel J. Danishefsky
    DOI:10.1021/ol062067i
    日期:2006.12.1
    Alder cascade was examined in the context of the natural product 11-O-debenzoyltashironin. Interestingly, the regioselectivity of the Diels-Alder reaction can be completely switched by changing the dienophile. Trapping of allyl alcohols during the oxidative dearomatization gives rise to the five-membered acetal, while trapping of allenyl alcohols results in the six-membered acetal. [reaction: see text]
    在天然产物11-O-脱苯甲酰tashironin的背景下检查了高价碘介导的氧化脱芳香化/ Diels-Alder级联反应。有趣的是,Diels-Alder反应的区域选择性可以通过改变亲二烯体来完全切换。在氧化脱芳香化过程中捕集烯丙醇会生成五元乙缩醛,而在捕集烯丙醇时会生成六元乙缩醛。[反应:看文字]
