  An efficient transformation of ethers to N,N′-disubstituted ureas in a Ritter type reaction

  摘要：

  A simple, mild, and an alternative protocol for the preparation of N,N'-disubstituted ureas from readily available ethers and cyanamides as starting materials is described. The protocol explores the reactivity of ether in a Ritter type reaction with cyanamide in the presence of BF3 center dot Et2O and resulting in the formation of N,N'-disubstituted urea. Divinyl ether as well as MTBE (methyl tert-butyl ether) can be employed as ether components to afford allyl and tert-butyl ureas respectively. (C) 2012 Elsevier Ltd. All rights reserved.

  A Pd/C‐catalyzed domino synthesis of symmetrical and unsymmetrical ureas from aryl iodides, sodium azide, amines and CHCl3 in water has been developed. This reaction proceeds with sequential carbonylation, Curtius rearrangement and nucleophilic addition. CHCl3 serves as a convenient and safe alternation of CO gas in the presence of KOH. A series of urea derivatives were obtained in moderate to good

  已经开发了一种Pd / C催化由水中的芳基碘化物，叠氮化钠，胺和CHCl 3合成对称和不对称脲的多米诺骨牌。该反应以顺序的羰基化，Curtius重排和亲核加成进行。在KOH存在下，CHCl 3可作为一种方便，安全的CO气体替代气体。以中等至良好的产率获得了具有良好的官能团耐受性的一系列脲衍生物。此外，连续六次运行后，Pd / C催化剂很容易被回收，催化活性略有下降。

  A set of Pd‐catalyzed ortho‐directed C—H glycosylation reactions with glycosyl chloride donors using various N‐linked bidentate auxiliaries has been developed for synthesis of C‐aryl glycosides. A broad range of pyranose and furanose moieties can be installed on the ortho position of arylamine, carbazole, indole and benzylamine type substrates in high yield and with high regio‐ and diastereoselectivity

• Photocatalyzed synthesis of unsymmetrical ureas via the oxidative decarboxylation of oxamic acids with PANI-g-C3N4-TiO2 composite under visible light

  The synthesis of unsymmetrical ureas via the photocatalyzed oxidative decarboxylation of oxamic acids has been developed. The carbamoyl radicals were generated from oxamic acids in the presence of a hypervalent iodine reagent and the PANI(Polyaniline)-g-C3N4-TiO2 composite under visible light irradiation. The radicals were converted in situ into the corresponding isocyanates, which were then trapped

  已经开发了通过光催化的草酰胺酸氧化脱羧合成不对称脲的方法。在高价碘试剂和PANI（聚苯胺）-gC 3 N 4 -TiO 2复合材料的存在下，由草酰胺酸在可见光照射下生成氨基甲酰基自由基。自由基被原位转化进入相应的异氰酸酯，然后被胺捕获，以中等至良好的产率得到相应的产物。该方案避免了直接使用对环境不利的异氰酸酯，并且可以耐受一系列底物。而且，光催化剂可以通过简单的过滤而容易地回收，并且可以在仅轻微降低催化活性的情况下重复使用几次。

  Described are various techniques that employ ion-exchange resins for the solution-phase synthesis of chemical libraries. We have found these resins to be useful as reagents and/or scavengers in a variety of reactions. Nine basic ion-exchange resins were evaluated for the catalysis and purification of an amide synthesized from an acid chloride. A number of the resins examined provided products in >95%
