sulfate radical anion, the utilization of this protocol in organic synthesis is rarely demonstrated. We reinvestigated selected K2S2O8-mediated known organic reactions that invariably require higher temperatures and an organic solvent. A diverse, mild functionalization and synthesis of heterocycles using the inexpensive oxidant K2S2O8 in water at room temperature is reported, demonstrating the sustainability
虽然在室温下使用葡萄糖进行过硫酸盐活化主要集中在硫酸根阴离子的动力学研究上,但很少证明该协议在有机合成中的应用。我们重新研究了选定的 K 2 S 2 O 8介导的已知有机反应,这些反应总是需要更高的温度和有机溶剂。据报道,在室温下,使用廉价的氧化剂 K 2 S 2 O 8在水中对杂环进行了多样化、温和的功能化和合成,证明了该方法的可持续性和广泛的范围。与用于过硫酸盐活化的传统方法不同,当前方法使用天然丰富的葡萄糖作为 K 2S 2 O 8活化剂,避免使用高温、紫外线、过渡金属或碱。
Synthesis of a new compound family, 1-aryl-3H-pyrrolo[2,1-d][1,2,5]triazepin-4(5H)-ones
5]triazepin-4(5H)-ones have been synthesized at our laboratory as bioisosters of biologically active 1-aryl-2,3-benzodiazepine-4-ones. The efficient synthetic route described applies the synthesis of 2-(2-aroylpyrrol-1-yl)acyl hydrazides followed by ring closure under acidic conditions. The N(3)-unsubstituted title compounds thus obtained can optionally be N-alkylated rendering the preparation of variously

inflammation, and psychiatric diseases. Recently, the CB2receptor has gained increased attention considering its crucial role in modulating neuroinflammation in several pathological conditions like neurodegenerative diseases. Here we describe the rational design of pyrrole-based analogues, which led to a potent and pharmacokinetically suitable CB2 full agonist particularly effective in improving cognitive
A series of 1-arylpyrrolo[1,2-a] pyrazine-3-carboxamides were designed and synthesized as 18 kDa translocator protein (TSPO) ligands. Anxiolytic-like activity of compounds was evaluated in the open field test and elevated plus maze test. Compounds 1a and 1b demonstrated high anxiolytic-like effect in the dose range of 0.1-1.0 mg/kg comparable with that of diazepam. The involvement of TSPO receptor in the mechanism of anxiolytic-like activity of new compounds was proved by antagonism of the most active compound 1a with TSPO selective inhibitor PK11195. In vitro binding studies demonstrated high TSPO affinities for compounds 1a and 1b. (C) 2015 Elsevier Ltd. All rights reserved.
