  A method for producing an arene with an aromatic C—N bond ortho to an aromatic C—O bond from a hydroxy arene comprising said aromatic C—O bond is provided. This method comprising the steps a) ortho-oxygenating the hydroxy arene to produce an ortho-quinone, b) condensating the ortho-quinone with a nitrogen nucleophile to generate a compound of Formula (IVa) or (IVb), and c) allowing 1,5-hydrogen atom shift of the compound of Formula (IVa) or (IVb), thereby producing arenes with a C—N bond ortho to a C—O bond of Formula (Va) and (Vb), respectively:

  提供一种从含有所述芳香C—O键的羟基芳烃制备具有芳香C—N键正交于芳香C—O键的芳烃的方法。该方法包括以下步骤：a) 对羟基芳烃进行正交氧化以产生一个正交醌，b) 将正交醌与氮亲核试剂缩合以生成化合物IVa或IVb的化合物，c) 允许化合物IVa或IVb发生1,5-氢原子转移，从而分别产生具有化合物Va和Vb的C—O键正交的C—N键的芳烃。
• Synthesis of a New Family ofN-Aryl Lactams Active on Chemesthesis and Taste

  A new class of synthetic compounds with chemesthetic activity has been identified. They have been designed ex-novo by structural similarity with known cooling compounds such as menthol, icilin and cyclic ketoenamines. 19 new derivatives have been obtained easily and in high yields by Goldberg arylation or lactam ring closure on the appropriate phenol or benzoic acid derivative. The synthetic procedures

  已鉴定出一类具有化学活性的新合成化合物。它们是通过与已知清凉化合物（如薄荷醇、西林和环酮烯胺）的结构相似性从头设计的。通过在适当的苯酚或苯甲酸衍生物上进行 Goldberg 芳基化或内酰胺环闭合，可以轻松且高收率地获得 19 种新衍生物。合成工艺适合克级制备，产物稳定，易于纯化。对 17 种新化合物进行了初步感官评估，其中 3 种表现出清凉活性，在某些情况下，口腔内有刺痛感。这些 N-芳基内酰胺似乎是一类有趣的化合物，需要扩大以推导出结构-活性关系。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany,

• Selective syntheses of benzoxazoles and N-(2-hydroxyaryl)pyrrolidin-2-ones from the corresponding cyclopropyl amides with PPh3/CX4
  作者：Yong-Hua Yang、Min Shi

  DOI：10.1016/j.tet.2005.11.077

  日期：2006.3

  Benzoxazoles 2 can be smoothly synthesized by treatment of starting materials of N-(2-hydroxyaryl) cyclopropyl amides 1 with PPh3/CCl4 in acetonitrile in good yields. When PPh3/CBr4/MS 4 was used in the reaction system, the corresponding ring-expanding products 3 were obtained in moderate to good yields in acetonitrile at 80 degrees C. Using DCE as a solvent in this reaction, the corresponding 2-(3-chloropropyl)benzoxazoles 5 were obtained as major products. (c) 2005 Elsevier Ltd. All rights reserved.
