  Synthesis of 1-carbamatoalkyl-2-naphthols in Tween® 20 Aqueous Micelles

  摘要：

  本文介绍了一种通过 2-萘酚、醛和氨基甲酸酯的单锅多组分反应制备 1-氨基甲酰基-2-萘酚的简便高效的方法。该反应在 75-80 °C 的中性条件下，在水介质中进行，非离子表面活性剂 Tween® A 的负载量为 20.5 wt% 的催化剂最为理想。反应结束后，催化剂可直接回收并重复使用，无需进一步处理。六次循环后，产品收率略有下降。除了水之外，还探讨了一些常见溶剂对反应的影响。在优化条件下，用各种醛类和氨基甲酸酯对这种多组分缩合反应的通用性进行了评估。

  Sulfamic acid-functionalised magnetic nanoparticles have been synthesised and used as efficient heterogeneous solid acid catalysts for the condensation of aromatic aldehydes with 2-naphthol and amides (or carbamates) via three-component reactions under solvent-free conditions at 80°C. Quantitative conversion of the reactants is achieved under mild conditions. Recovery of the catalyst is easily achieved by ‘magnetic decantation’. The supported catalyst is reused four times without any significant degradation in catalytic activity.

  日期：——

  A highly efficient synthesis of carbamatoalkyl naphthols has been performed by a one-pot three-component condensation of 2-naphthol, aldehydes, and methyl/ethyl/benzyl carbamates in the presence of cerium ammonium nitrate under solvent-free conditions at 70 oC. The solvent, optimal amounts of raw materials and catalyst, and reaction temperature are investigated. Experimental results show that only 0.1 mmol catalyst is enough to induce the conversion. Most reactions are performed within a short reaction time. The structures of all products were characterized by IR, 1H NMR, 13C NMR, MS, and elemental analysis. A mechanism to rationalize the reaction has been proposed.

  在无溶剂条件下，在70℃下，通过2-萘酚、醛类和甲基/乙基/苄基氨基甲酸酯在硝酸铈铵存在下的一锅三组分缩合，实现了氨基甲酸烷基萘酚的高效合成。对溶剂、最佳原料用量和催化剂以及反应温度进行了研究。实验结果表明，仅0.1mmol催化剂就足以引发转化。大多数反应在较短的反应时间内完成。通过红外光谱、1H核磁共振、13C核磁共振、质谱和元素分析对所有产物的结构进行了表征。提出了反应的合理化机制。
