  三甲基甲硅烷基三氟甲磺酸盐促进的β-酮烯酰胺的环缩合反应，以及随后的非硝化反应，生成壬基磺酸吡啶-2-基和吡啶-4-基壬酸酯，作为多取代吡啶的柔性前体

  摘要：

  献给恩斯特·绍曼（Ernst Schaumann）教授70岁生日之际 抽象 研究了使用KO t -Bu或三甲基甲硅烷基三氟甲磺酸盐/Hünig碱将β-酮烯酰胺分子内缩合为2-和/或4-吡啶酮衍生物。随后环化产物不被烧蚀，可以通过Suzuki-Miyaura偶联剂轻松纯化并进一步官能化，从而产生新的高度取代的吡啶衍生物。讨论了环缩合的区域选择性对β-酮烯酰胺结构的依赖性。 研究了使用KO t -Bu或三甲基甲硅烷基三氟甲磺酸盐/Hünig碱将β-酮烯酰胺分子内缩合为2-和/或4-吡啶酮衍生物。随后环化产物不被烧蚀，可以通过Suzuki-Miyaura偶联剂轻松纯化并进一步官能化，从而产生新的高度取代的吡啶衍生物。讨论了环缩合的区域选择性对β-酮烯酰胺结构的依赖性。

  In this article, we report a base-promoted sequential cyclization/aldol-type condensation/isomerization cascade reaction of N-propargyl-β-enaminones with aryl aldehydes. The key step in this protocol is the generation of 1,4-oxazepine anions from N-propargyl-β-enaminones under basic conditions, which are captured by aryl aldehydes. The method allows the formation of one pyridone core and one C—C double

  在本文中，我们报告了N-炔丙基-β-烯胺酮与芳醛的碱促进顺序环化/羟醛型缩合/异构化级联反应。该协议的关键步骤是在碱性条件下从N-炔丙基-β-烯胺酮生成 1,4-氧氮杂阴离子，这些阴离子被芳醛捕获。该方法允许在“一锅”中形成一个吡啶酮核和一个CC双键，并以中等至良好的收率制备多种具有广泛官能团耐受性的致密修饰的吡啶酮衍生物。
• 2-Pyridones from Cyanoacetamides and Enecarbonyl Compounds:  Application to the Synthesis of Nothapodytine B

  The condensation of an enone or enal with cyanoacetamide derivatives and t-BuOK furnishes either 3-eyano-2-pyridones or 3-unsubstituted-2-pyridones, depending on whether the reaction is carried out in the presence or in the absence Of O-2. In the first case, in situ oxidation of Michael-type intermediates takes place; in the second case, the products result from "decyanidative aromatization" of such intermediates. A one-step synthesis of 3-alkyl-2-pyridones has been devised on the basis of decyanative union of an enone/enal and a 2-alkyleyanoacetamide. The new reaction forms the centerpiece of an unusually concise synthesis of nothapodytine B (mappicine ketone).

  Base-promoted reactions of benzotriazolyl-containing acetic acid derivatives, 2-(benzotriazol-1-yl)acetonitrile (7a), 2-(benzotriazol-1-yl)acetamide (7b), and (+/-)-2-(benzotriazol-1-yl)propionamide (7c), with alpha,beta-unsaturated ketones 8 give efficient and regioselective access to previously difficult to attain 3-unsubstituted pyridine derivatives: the 2-(substituted amino)pyridines 14a-k and the 4,6-substituted pyrid-2-ones 15a-h. The pyridine rings result from tandem [3 + 3] annulations involving a Michael addition followed by cyclization.
