• Lewis Acid-Mediated Reactions of Alkyl Azides with α,β-Unsaturated Ketones
  作者：D. Srinivasa Reddy、Weston R. Judd、Jeffrey Aubé

  DOI：10.1021/ol0355130

  日期：2003.10.1

  [reaction: see text] Alkyl azides react with saturated ketones upon treatment with Lewis acids to afford ring-expansion products through the azido-Schmidt reaction, but this reaction does not proceed when alpha,beta-unsaturated ketones are used. In this study, alkyl azides were reacted with enones in the presence of Lewis acids to give enaminones (vinylogous amides), which formally involve a ring contraction

  Aryl glycosides represent a group of molecules with immense biological applications and implications. While the syntheses of aryl C-glycosides and O-glycosides have been studied extensively, the preparation for aryl N-glycosides is relatively unexplored. By employing 1,4-naphthoquinone and glycosyl azides undergoing a [3 + 2] cycloaddition, we have developed a convenient method for constructing three

  芳基糖苷代表了一组具有巨大生物学应用和意义的分子。虽然已经广泛研究了芳基C-糖苷和O-糖苷的合成，但是相对未开发芳基N-糖苷的制备方法。通过使用经历[3 + 2]环加成反应的1,4-萘醌和糖基叠氮化物，我们开发了一种便捷的方法来构建包括N在内的三类不同的芳基N-糖苷-通过溶剂控制将糖基化的2-氨基亚甲基-1,3-茚满二酮，苯并ze庚因-1,5-二酮和9,10-蒽醌衍生物。发现在DMF中进行环加成仅形成9,10-蒽醌衍生物，而极性较小的溶剂如甲苯提供所有三个芳基N-糖苷。N-糖基化的9，10-蒽醌衍生物的合成是特别令人感兴趣的，因为没有已知的例子被记录。这些氮的合成使用传统糖基化方法的β-糖基化杂环化合物可能具有挑战性。因此，我们面向多样性的协议可以看作是一种替代性的实用糖基化方法。另外，我们还证明了烷基叠氮化物也可以经历相同的环加成，进一步扩大了可用于更广泛兴趣的结构库。最初的抗癌检测表明19f和19k分别产生17
• Divergent and facile Lewis acid-mediated synthesis of N-alkyl 2-aminomethylene-1,3-indanediones and 2-alkylamino-1,4-naphthoquinones

  N-Alkyl 2-aminomethylene-1,3-indanediones and 2-alkylamino-1,4-naphthoquinones are known for their diverse and versatile bioactivities and applications. Traditionally, these two compounds were synthesized in separate routes using different materials. By employing Lewis acid, cycloaddition of alkyl azides and 1,4-naphthoquinone can provide these two classes of compound in one-pot fashion. Among the Lewis acids and conditions examined, TMSOTf under reflux offers the best overall yields. In addition, the purification of both classes of compounds can be easily achieved using flash column chromatography making this methodology feasible for scale-up synthesis of compounds with biological interests.
