  A series of new heterocyclic derivatives having a pyridine nucleus were synthesized. 4-(5-(2-Chlorophenyl)-4H-1,2,4-triazol-3-yl)pyridine (7c) and 4-(5-(2-Nitrophenyl)-4H-1,2,4-triazol-3-yl)pyridine (7d) presented the best analgesic profie of this series in hot-plate, tail-flick, and formalin-induced licking tests, which was partially prevented by pretreatment with mecamylamine, a nicotinic receptor

  thermogravimetric analysis, and BET analysis. The FeNPs were amorphous in nature with average particle size ~ 19 nm and successfully employed as heterogeneous catalyst for the synthesis of quinoxaline, benzimidazole, and pyrazole derivatives in aqueous medium at ambient conditions. The FeNPs could be recycled up to five times with modest change in the catalytic activity. Graphic abstract

  摘要 我们已经报告了可再生天然资源乳香锯缘青蟹植物的叶片提取物的无定形铁纳米颗粒（FeNPs）的合成，表征和催化应用。通过添加金合欢荚果荚提取物原位稳定合成的FeNPs作为生物表面活性剂（pH 3.11）。使用紫外可见光谱，X射线衍射分析，选定区域电子衍射，能量色散X射线光谱，扫描电子显微镜，透射电子显微镜，X射线光电子光谱，热重分析，和BET分析。FeNPs本质上是无定形的，平均粒径约为19 nm，已成功地用作在环境条件下在水性介质中合成喹喔啉，苯并咪唑和吡唑衍生物的非均相催化剂。FeNPs可以循环使用多达五次，而催化活性变化不大。 图形摘要
• Hydrotrope: green and rapid approach for the catalyst-free synthesis of pyrazole derivatives

  An efficient synthesis of pyrazole derivatives by condensation of 1,3-diketone and hydrazines/hydrazides has been achieved in aqueous hydrotropic solution under catalyst-free conditions within a very short time. The present protocol is beneficial as it includes mild reaction conditions, shorter reaction times, use of universal solvent water, which avoids volatile organic solvents, high yields of products, and being environmentally friendly.
• An efficient practical chemo-enzymatic protocol for the synthesis of pyrazoles in aqueous medium at ambient temperature

  An expeditious oxidative cyclocondensation reaction of hydrazines/hydrazides with 1,3-dicarbonyl compound was efficiently developed in aqueous medium using Saccharomyces cerevisae (baker's yeast) as a whole cell biocatalyst at room temperature. The method has been assigned using green chemistry measures and found to give a range of N-substituted pyrazoles with moderate to excellent yields (70-92%). The reaction progress was monitored by gas chromatography. (C) 2015 Elsevier B.V. All rights reserved.
