• Synthesis of biologically as well as industrially important 1,4,5-trisubstituted-1,2,3-triazoles using a highly efficient, green and recyclable DBU–H2O catalytic system

  Substituted 1,2,3-triazoles are important heterocyclic molecules with applications in diverse research areas. 1,3-Dipolar cycloaddition reaction of azides and enolizable compounds is an important method of generating substituted 1,2,3-triazoles. However, the reported methods in the literature for 1,3-cycloaddition of aryl azides involve long reaction time, use of hazardous/volatile reagents, and toxic organic solvents. In this paper we have reported the novel environment friendly protocols for the synthesis of 1,4,5-trisubstituted-1,2,3-triazoles by reaction of various aryl azides with active methylene compounds in a DBU–water system under conventional heating, ultrasonic and microwave irradiation. The methodologies defined herein showed synthetic advantages in terms of high atom economy, low environmental impact, mild reaction conditions and good yields in shorter reaction time and recyclability of the reaction medium.

  取代的1,2,3-呫唑是重要的杂环分子，在多个研究领域具有应用。叠氮化物与可烯醇化合物的1,3-极性环加成反应是一种生成取代1,2,3-呫唑的重要方法。然而，文献中报道的芳香叠氮化物的1,3-环加成方法涉及较长的反应时间、使用危险/挥发性试剂以及有毒的有机溶剂。在本文中，我们报道了通过在DBU-水体系中对各种芳香叠氮化物与活性亚甲基化合物进行反应，合成1,4,5-三取代-1,2,3-呫唑的新型环保合成方法，反应条件为传统加热、超声波和微波照射。这里定义的方法在合成上具有高原子经济、低环境影响、温和反应条件以及在较短反应时间内获得良好产率和反应介质的可回收性等优点。

  Continuous flow processing was applied for the rapid replacement of an aromatic amino group with a hydride. The approach was applied to a range of aromatic heterocycles, confirming the wide scope and substituent-tolerance of the processes. Flow equipment was utilized and the process optimised to overcome the problematically-unstable intermediates that have restricted yields in previous studies relying

  β-dicarbonyl compounds with their enol forms, a 1,3-dipolar cycloaddition of the enol forms with the aryl azides (high activation energy), and a dehydration process (lower activation energy). The effect of non-conventional activation methods on the degradation of 1,2,3-triazolines was next studied experimentally. Finally, some of the 1,2,3-triazoles such synthesized were evaluated for their bactericidal and

  Si-MCM-41, Ga-MCM-41 and Al-MCM-41 mesoporous catalysts (with Si/Al = 80 and Si/Ga = 80) were prepared by direct synthesis under hydrothermal crystallization method using sodium aluminate or gallium sulfate and tetraethyl orthosilicate (TEOS) as aluminum or gallium and silica sources, respectively. The structural features of the materials were determined by various physico-chemical techniques such as X-ray diffraction (XRD), nitrogen sorption at 77K, Fourier transform infrared spectroscopy (FTIR), scanning and transmission electronic microscopy (SEM, TEM) and thermogravimetric analysis ATG. The catalytic activity of the calcined and as-synthesized catalyst was evaluated through the cycloaddition reaction of 4-nitrophenyl azide with activated alkenes at room temperature under liquid-phase conditions. High yields of 1,2,3-triazole were obtained. For comparison purpose, mixtures of homogeneous and heterogeneous catalyst Et3N/M-MCM-41 (M = Al or Ga) are also tested. The catalyst was used in five consecutive experiments without important loss of activity, confirming its stability. Finally, a new method for preparing triazoles in short reaction times was developed. (C) 2014 Elsevier B.V. All rights reserved.
