  Convenient and Practical One-Pot Synthesis of 4-Chloropyrimidines via a Novel Chloroimidate Annulation

  摘要：

  Reaction of aromatic or heteroaromatic 2-acyl(amino)nitriles with phosphorus pentachloride triggers a novel chloroimidate cyclization, leading directly to the corresponding annullated 4-chloropyrimidines in good to excellent yields. The reaction lends itself to the telescoped one-pot construction of 4-functionalized pyrimidines from the corresponding (hetero)aromatic 2-aminonitriles. For a pyrazolopyrimidine development intermediate, this reaction was scaled up to multikilogram scale with excellent results. A total of 10 examples with different substrates are provided. This one-pot reaction provides an attractive and sustainable alternative to the commonly used multistep methodology for this transformation.

  C−H activation is a versatile tool for appending aryl groups to aromatic systems. However, heavy demands on multiple catalytic cycle operations and site‐selectivity have limited its use for graphene segment synthesis. A Pd‐catal‐ yzed one‐step synthesis of functionalized triphenylene frameworks is disclosed, which proceeds by 2‐ or 4‐fold C−H arylation of unactivated benzene derivatives.

  The synthesis of 2,4-disubstituted quinazolines by a palladium-catalyzed reaction of arylboronic acids with N-(2-cyanoaryl)benzamides has been developed with moderate to excellent yields. The method shows good functional group tolerance. In particular, halogen and hydroxyl substituents, which are amenable for further synthetic elaborations, are well tolerated. Moreover, the present synthetic route

  已经开发了通过钯催化的芳基硼酸与N-（2-氰基芳基）苯甲酰胺的反应合成2,4-二取代的喹唑啉，其产率中等至优异。该方法显示出良好的官能团耐受性。特别是，对于进一步的合成修饰而言，卤素和羟基取代基是很好的耐受性。而且，本合成路线可以容易地按比例放大至克量而没有困难。该机制可能涉及亲核加成腈功能，形成亚胺中间体，然后分子内加成酰胺并脱水成喹唑啉环。

• Copper-Catalyzed Oxidative Ring Closure of<i>ortho</i>-Cyanoanilides with Hypervalent Iodonium Salts: Arylation-Ring Closure Approach to Iminobenzoxazines
  作者：Klára Aradi、Zoltán Novák

  DOI：10.1002/adsc.201400763

  日期：2015.2.9

  AbstractA novel, highly modular synthetic methodology with high functional group tolerance was developed for the construction of iminobenzoxazine derivatives from ortho‐cyanoanilides and diaryliodonium triflates via an oxidative arylation–cyclization path. The reaction is supposed to involve the formation of highly active aryl‐copper(III) species. In this novel transformation, copper(II) triflate was used as catalyst in 1,2‐dichloroethane or ethyl acetate and the reaction takes place at 75 °C in 2–16 h.magnified image
