  Studies toward the Unique Pederin Family Member Psymberin: Full Structure Elucidation, Two Alternative Total Syntheses, and Analogs

  摘要：

  Two synthetic approaches to psymberin have been accomplished. A highly convergent first generation synthesis led to the complete stereochemical assignment and demonstrated that psymberin and irciniastatin A are identical compounds. This synthesis featured a diastereoselective aldol coupling between the aryl fragment and a central tetrahydropyran core and a novel one-pot procedure to convert an amide, via intermediacy of a sensitive methyl imidate, to the N-acyl aminal reminiscent of psymberin. The highlights of the second generation synthesis include an efficient iridium-catalyzed enantioselective bisallylation of neopentyl glycol and a stepwise Sonogashira coupling/cycloisomerization/reduction sequence to construct the dihydroisocoumarin unit. The two synthetic avenues were achieved in 17-18 steps (longest linear sequence, similar to 14-15 isolations) from 3 fragments prepared in 7-8 (first generation) and 3-8 (second generation) steps each. This convergent approach allowed for the preparation of sufficient amounts of psymberin (similar to 0.5 g) for follow-up biological studies. Meanwhile, our highly flexible strategy enabled the design and synthesis of multiple analogs, including a psymberin pederin hybrid, termed psympederin, that proved crucial to a comprehensive understanding of the chemical biology of psymberin and related compounds that will be described in a subsequent manuscript.

  N-acyl aminal and functional groups in the two major subunits on biological activity. These analogs, including a pederin/psymberin chimera, were analyzed for their growth inhibitory effects, revealing several new potent cytotoxins and leading to postulates regarding the molecular conformational and hydrogen bonding patterns that are required for biological activity. Second generation analogs have been

  有效的细胞毒素 pederin 和 psymberin 是通过简洁的合成路线（最长线性序列中分别为 10 和 14 步）制备的，这些路线通过后期多组分方法构建 N-酰基氨基键。该路线允许轻松制备许多类似物，这些类似物旨在探索 N-酰基氨基中的烷氧基和两个主要亚基中的官能团对生物活性的重要性。这些类似物，包括 pederin/psymberin 嵌合体，分析了它们的生长抑制作用，揭示了几种新的有效细胞毒素，并导致关于生物活性所需的分子构象和氢键模式的假设。第二代类似物已根据初始测定的结果和这些化合物与核糖体结合的基于结构的模型制备。报道了这些化合物的生长抑制特性。这些研究表明，一般的有机化学，特别是后期多组分反应，在开发独特而有效的生物反应效应物方面可以发挥深远的作用。
