  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.

  natural product in a longest linear sequence of 18 steps. Biological testing of synthetic biselide A suggests this macrolide disrupts cell division through a mechanism related to the regulation of microtubule cytoskeleton organization. Overall, this concise synthesis and insight gained into the mechanism of action should inspire medicinal chemistry efforts directed at structurally related anticancer

  描述了海洋大环内酯双己内酯 A 的全合成，其依赖于对映体富集的 α-氯醛作为唯一的手性结构单元。提出了构建大环的几种策略，包括大环 Reformatsky 反应，该反应最终以 18 个步骤的最长线性序列提供天然产物。合成双塞内酯 A 的生物学测试表明，这种大环内酯通过与微管细胞骨架组织调节相关的机制破坏细胞分裂。总的来说，这种简明的合成和对作用机制的深入了解应该会激发针对结构相关的抗癌海洋大环内酯的药物化学研究。
