  Concise Synthesis of 2-Benzazepine Derivatives and Their Biological Activity

  摘要：

  2-Benzazepines, which are potentially good candidates for new drug therapies to treat skin wounds, were readily prepared from substituted cinnamylamide via an intramolecular Friedel Crafts reaction. With few steps and effective reactions, the procedure enables a rapid derivatization of 2-benzazepines. Moreover, optically active 4-substituted-2-benzazepines were prepared from chiral alpha-substituted cinnamylamides, which were readily prepared by asymmetric alpha-alkylation of chiral cinnamyl oxazolidinone amides. We have easily prepared a library of more than 20 derivatives and examined the biological activity of the compounds.

  6 with potassium hydroxide or sodium methoxide in methanol at room temperature provides 1,2-dihydro[c]benzazepin-3-ones 9. The high product yields and the ease of the reactions under surprisingly mild conditions are particularly intriguing in view of the complex mechanistic pathway involved in the overall transformation. A mechanism based on a multistep rearrangement is proposed, involving conjugated

  在室温下在甲醇中用氢氧化钾或甲醇钠处理各种 6 型邻炔基芳基硝酮提供 1,2-二氢 [c] 苯并氮杂 9。在令人惊讶的温和条件下，产物产率高且反应容易考虑到整个转化过程中涉及的复杂机制途径，这些条件特别有趣。提出了一种基于多步重排的机制，涉及 13 型共轭丙二烯硝酮作为 1,7-偶极环化过程的前体，随后进行进一步的键重组，环丙酮 16 作为关键中间体。与丙二烯形成一致的是，使用三键异构体 12 和 37 可以实现相同的转化，它们包含末端烷基。异吲哚20作为次要产物的竞争形成支持环丙酮16的中间体。在用碱处理二氢萘并环化的硝酮 30 时，主要产物氮杂酮 31 的形成还伴随着异构异吲哚 32 的形成。一些选择性的 C=O 和 C=C 氢化反应，以及转化为硫酮 42和乙烯基溴 9p，已经用 9 的代表性例子进行了证明。
