  Total Synthesis of Cortistatins A and J

  摘要：

  This paper describes the details of our synthetic studies on the marine steroidal alkaloids cortistatins A and J. The key features of our strategy include (i) an efficient Knoevenagel/electrocyclic strategy to couple the diketone and the CD-ring fragment, (ii) a chemoselective radical cyclization to construct the oxabicyclo[3.2.1]octene B-ring system, (iii) a highly stereocontrolled installation of the isoquinoline unit, and (iv) a late-stage functionalization of the A-ring.

  antiproliferative natural products cortistatins A (1) and J (5) in their naturally occurring enantiomeric forms are described. The modular and convergent strategy employed relies on an intramolecular oxa-Michael addition/aldol/dehydration cascade reaction to cast the ABCD ring framework of the molecule and both Sonogashira and Suzuki-Miyaura coupling reactions to assemble the necessary building blocks into the

  描述了天然存在的对映体形式的高选择性抗增殖天然产物皮质抑素 A (1) 和 J (5) 的全合成。采用的模块化和收敛策略依赖于分子内 oxa-Michael 加成/醛醇/脱水级联反应来铸造分子的 ABCD 环框架以及 Sonogashira 和 Suzuki-Miyaura 偶联反应，以将必要的构建块组装成所需的七环骨架。来自后期环氧酮的不同方法以立体选择性方式导致两个目标分子。开发的合成技术被应用于构建皮质抑素的几种类似物，这些类似物经过生物学评估，并与天然产物在抗多种癌细胞的抗增殖活性方面进行了比较。发现缺乏皮质抑素 A 的二甲氨基和羟基的类似物 8 和 81 表现出与母体化合物相当的生物活性，从而得出这样的结论，即这些功能对生物活性不是必需的。

  The cortistatins are a recently identified class of marine natural products characterized by an unusual steroidal skeleton, which have been found to inhibit differentially the proliferation of various mammalian cells in culture by an unknown mechanism. We describe a comprehensive route for the synthesis of cortistatins from a common precursor, which in turn is assembled from two fragments of similar

  皮质抑素是最近发现的一类海洋天然产物，其特征是具有不寻常的甾体骨架，已发现其通过未知机制不同程度地抑制培养中各种哺乳动物细胞的增殖。我们描述了从一个共同的前体合成皮质抑素的综合路线，而后者又由两个结构复杂性相似的片段组装而成。皮质抑素 A 和 J，以及 K 和 L 首次在平行过程中从由单一化合物制备的类似中间体合成。通过鉴定将皮质抑素 L 合成系列中的中间体与皮质抑素 A 和 J 的相应中间体联系起来的简便实验室转化，我们推测自然界中可能会发生一些相关的路径，
