A porous cross‐linked poly (ethyleneamine)‐polysulfonamide (PEA‐PSA) as a novel organic support system is synthesized in the presence of silica template by nanocasting technique. The paper demonstrates immobilization of CuI nanoparticles inside the pores (PEA‐PSA@CuI) for the facile recovery and recycling of these nanoparticles. The presence of porous PEA‐PSA and PEA‐PSA@CuI nanocomposites was confirmed
在二氧化硅模板的存在下,通过纳米浇铸技术合成了一种多孔的交联聚(亚乙基胺)-聚磺酰胺(PEA-PSA)作为一种新型的有机载体体系。本文证明了将CuI纳米粒子固定在孔内(PEA-PSA @ CuI)可以方便地回收和再循环这些纳米粒子。使用FT-IR光谱,FE-SEM,EDX,TGA,XRD,TEM,BET,XPS,WDX,1 H NMR和ICP-OES技术确认了多孔PEA-PSA和PEA-PSA @ CuI纳米复合材料的存在。PEA-PSA @ CuI与Ag(I)/ K 2 S 2 O 8一起作为p的N-芳基化中可重复使用的协同催化剂-氧化剂体系而实现-甲苯磺酰胺与温和的取代羧酸。因此,已经开发了由铜和银催化的新型脱羧交叉偶联。芳族,仲和叔脂肪酸与对甲苯磺酰胺经过高效脱羧过程,得到相应的产物。该方法为从容易负担的底物上灵活合成磺酰胺提供了一种实用的方法。该催化剂是高度可重复使用和有效的,特别是在所需产物的时间和产率方面。
2-Sulfonyliminodihydropyrimidines: A Novel Class of Analgesic Compounds
antinociceptive and anti‐inflammatory activities. The results were compared with that of acetyl salicylic acid. Compounds 6Ab–d and 6Be displayed an interesting analgesic profile in the acetic acid‐induced abdominal contractions test. Based on the results of the carrageenan‐hind paw edema test, compound 6Af showed potential anti‐inflammatory activity.

A protocol for three-component reactions of cyclic ethers, α-diazo esters, and weak nitrogen, oxygen, carbon, and sulfur nucleophiles (pKa = 2.2–14.8) to afford a variety of structurally complex α-oxyalkylated esters is reported. These reactions involve intermolecular activation of the cyclic ether (present in excess) by the α-diazo ester to form an oxonium ylide under metal-free conditions, followed
据报道,存在一种用于环醚,α-重氮酯与弱氮,氧,碳和硫亲核试剂(p K a = 2.2–14.8)的三组分反应的协议,该反应可提供多种结构复杂的α-氧基烷基化酯。这些反应包括在无金属条件下,α-重氮酯对环状醚(过量存在)进行分子间活化,形成叶立德叶立酮,然后由亲核试剂开环。
