  Eosin Y Catalyzed Visible-Light-Promoted Aerobic Oxidative Cyclization of 2-Aminobenzothiazole

  摘要：

  A mild and efficient one-pot visible light irradiated synthesis of 2-aminobenzothiazole 4(a-l) from arylisothiocyanate 1(a-l) and secondary amines 2 have been reported in presence of eosin Y as an organophotoredox catalyst at room temperature under aerobic condition. This synthesis includes application of air and visible light as inexpensive, readily available, high atom economy, non-toxic and sustainable regents.

• Highly efficient and catalyst-free synthesis of unsymmetrical thioureas under solvent-free conditions

  A highly efficient and simple synthesis of unsymmetrical thioureas is reported based on the reaction of readily synthesized dithiocarbamates with amines, without using any catalyst under solvent-free conditions. The short reaction time, high yields, and solvent-free conditions are advantages of this method. We did not observe the formation of any symmetric disubstituted thiourea, under these reaction

  据报道，基于容易合成的二硫代氨基甲酸酯与胺的反应，无需在无溶剂条件下使用任何催化剂，即可高效且简单地合成不对称硫脲。反应时间短，产率高和无溶剂条件是该方法的优点。在这些反应条件下，我们没有观察到任何对称的二取代硫脲的形成。
• Arylthioureas with bromine or its equivalents gives no ‘Hugerschoff’ reaction product

  The in situ generated aryl–alkyl unsymmetrical thiourea obtained by the reaction of an aryl isothiocyanate with an aliphatic secondary amine on treatment with bromine or its equivalent gave exclusively a product having a thioamido guanidino moiety and not the expected Hugerschoff product 2-aminobenzothiazole. A plausible reaction mechanism has been proposed for this unprecedented transformation and the scope has been extended to various substrates.

  通过将芳基异硫氰酸酯与脂肪族二级胺反应得到的原位生成的不对称芳基-烷基硫脲，在用溴或其等效物处理后，独占性地产生了具有硫酰氨基呱啶部分的产物，而不是预期的Hugerschoff产物2-氨基苯并噻唑。提出了一种合理的反应机制来解释这一前所未有的转化，并且将适用范围扩展到了各种底物。

  A new and efficient method for the synthesis of thiourea derivatives by a sequential one-pot, three-component reaction between aromatic isocyanides, amines, and 1,2-di-tert-butyldisulfane (DTBS) was developed and 27 different examples were synthesized in good to excellent yields. DTBS was identified as an effective sulfur surrogate without the use of both catalysts and solvents. This protocol does
