  • Prins Reaction of Homoallenyl Alcohols: Access to Substituted Pyrans in the Halichondrin Series
    作者:Hyeong-wook Choi、Francis G. Fang、Hui Fang、Dae-Shik Kim、Steven R. Mathieu、Robert T. Yu
    DOI:10.1021/acs.orglett.7b02934
    日期:2017.11.17
    Prins reaction of homoallenyl alcohols with aldehyde dimethylacetals in the presence of methoxyacetic acid directly affords tetrasubstituted pyrans relevant to halichondrins with complete control of the C27 stereogenic center. Regioselective Tsuji reduction of the resultant allylic acetates stereoselectively establishes the C25 stereogenic center and C26 exocyclic olefin. Building upon these findings
    甲氧基乙酸的存在下高烯丙基醇与醛二甲基乙缩醛的Prins反应直接得到与卤代软骨素相关的四取代的喃,并完全控制C27立体异构中心。产生的烯丙基乙酸酯的区域选择性Tsuji还原立体选择性地建立了C25立体异构中心和C26环外烯烃。基于这些发现,我们可以简便地获得利康定C14–C38和eribulin C14–C35片段。

    coupling partners. The C23-O bond is stereospecifically constructed via reductive cyclization of the oxonium ion, or oxy-Michael cyclization. Both syntheses have a high overall efficiency: E7389 C14-C35 and halichondrin C14-C38 building blocks have been synthesized from the corresponding C27-C35 and C27-C38 aldehydes, respectively, in high overall yields with an excellent stereoselectivity. Because of
    Cr 介导的偶联反应通常在给定亲核试剂略微过量的情况下实现。为了开发该过程的经济有效的使用,已经研究了两种不同的方法。第一种方法依赖于两个连续的催化不对称 Cr 介导的偶联,偶联伙伴的使用有意使分子大小和复杂性不平衡。第二种方法依赖于确定亲核试剂的成功,这使我们能够以 1:1 的偶联伙伴摩尔比令人满意地实现偶联。C23-O 键是通过氧鎓离子的还原环化或氧-迈克尔环化立体有择地构建的。两种合成都具有较高的整体效率:E7389 C14-C35 和软海绵素 C14-C38 构建块已由相应的 C27-C35 和 C27-C38 醛合成,分别以高总产率和优异的立体选择性。由于操作简单,本文概述的合成似乎非常适合缩放。

    The invention provides methods for the synthesis of eribulin or a pharmaceutically acceptable salt thereof (e.g., eribulin mesylate) through a macrocyclization strategy. The macrocyclization strategy of the present invention involves subjecting a non-macrocyclic intermediate to a carbon-carbon bond-forming reaction (e.g., an olefination reaction (e.g., Homer-Wadsworth-Emmons olefination), Dieckmann reaction, catalytic Ring-Closing Olefin Metathesis, or Nozaki-Hiyama-Kishi reaction) to afford a macrocyclic intermediate. The invention also provides compounds useful as intermediates in the synthesis of eribulin or a pharmaceutically acceptable salt thereof and methods for preparing the same.
