  • New Syntheses of E7389 C14−C35 and Halichondrin C14−C38 Building Blocks: Reductive Cyclization and Oxy-Michael Cyclization Approaches

    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。
  • Dramatic Improvement in Catalyst Loadings and Molar Ratios of Coupling Partners for Ni/Cr-Mediated Coupling Reactions: Heterobimetallic Catalysts
    作者:Xiang Liu、James A. Henderson、Takeo Sasaki、Yoshito Kishi
    DOI:10.1021/ja9079308
    日期:2009.11.25
    Two new ligands 1a,b are reported. Upon treatment with 1 equiv of NiCl2 center dot(MeOCH2)(2), 1a,b give the corresponding Ni complexes. X-ray analysis of 1a-NiCl2 established that the NiCl2 is selectively coordinated to the phenanthroline nitrogens. Ni/Cr heterobimetallic catalysts 1a,b center dot CrCl2/NiCl2, prepared from 1a,b center dot NiCl2, have been shown to behave exceptionally well in catalytic asymmetric Ni/Cr-mediated couplings, with highlights including the following: (1) 1-2 mol % catalyst is sufficient to complete the coupling; (2) only negligible amounts of the dimers, byproducts formed through the alkenyl Ni species, are observed; (3) the coupling goes to completion even with a 1:1 molar ratio of the coupling partners; and (4) the asymmetric induction is practically identical with that obtained from the coupling with the Cr catalysts prepared from (S)-sulfonamides 2a,b. The scope of the new Ni/Cr heterobimetallic catalysts was briefly studied using four additional aldehydes. The applicability of the new catalysts to polyfunctional substrates was demonstrated by two C-C bond formations chosen from the hatichondrin/E7389 synthesis as examples.
