  • Design, synthesis, and in vitro hMAO-B inhibitory evaluation of some 1-methyl-3,5-diphenyl-4,5-dihydro-1H-pyrazoles
    作者:Rossella Fioravanti、Nicoletta Desideri、Mariangela Biava、Luca Proietti Monaco、Laura Grammatica、Matilde Yáñez

    日期:2013.9
    A series of 1-methyl-3,5-diphenyl-4,5-dihydro-1H-pyrazoles (3a–k and 4a–u) were designed, synthesized, and evaluated for their inhibitory efficacy towards the two hMAO isoforms. Most of the derivatives were found to be potent and selective hMAO-B inhibitors. In particular, derivative 3g showed greater hMAO-B affinity than selective inhibitor selegiline coupled with high selectivity index (SI = 145)

    A new and simple method for the stereospecific synthesis of 3,5-disubstituted-4,5-dihydro-isoxazoles (chiral isoxazolines) from readily available oximes of chiral Michael adducts of thiophenol to chalcones is reported. An analogous reaction with the N-arylhydrazones of the Michael adduct gave nonracemic 1-(aryl)-3,5-diphenyl-4,5-dihydro-1H-pyrazoles (chiral pyrazolines), but these products are configurationally

    Pyrazoles are a very important structural motif widely found in pharmaceuticals and agrochemicals. An electrochemically enabled approach for the sustainable synthesis of pyrazoles via oxidative aromatization of pyrazolines is presented. Inexpensive sodium chloride is employed in a dual role as a redox mediator and supporting electrolyte in a biphasic system (aqueous/organic). The method is applicable

    Abstract

    Porous organic polymers (POPs), and especially covalent triazine frameworks (CTFs), are being developed as the next generation of metal‐free heterogeneous photocatalysts. However, many of the current synthetic routes to obtain these photoactive POPs require expensive monomers and rely on precious metal catalysts, thus hindering their widespread implementation. In this work, a range of POPs was synthesized from simple unfunctionalized aromatic building blocks, through Lewis acid‐catalyzed polymerization. The obtained materials were applied, for the first time, as heterogeneous photocatalysts for the aromatization of N‐heterocycles. With the use of the most active material, denoted as CTF‐Pyr, which consists of photoactive pyrene and triazine moieties, a wide range of pyridines, dihydroquinoline‐5‐ones, tetrahydroacridine‐1,8‐diones and pyrazoles were obtained in excellent yields (70–99 %). Moreover, these reactions were carried out under very mild conditions using air and at room temperature, highlighting the potential of these materials as catalysts for green transformations.

    摘要 多孔有机聚合物(POPs),尤其是共价三嗪框架(CTFs),正被开发为下一代无属异相光催化剂。然而,目前获得这些光活性持久性有机聚合物的许多合成路线都需要昂贵的单体并依赖贵金属催化剂,因此阻碍了它们的广泛应用。在这项研究中,我们通过路易斯酸催化聚合反应,从简单的非官能化芳香族结构单元合成了一系列持久性有机污染物。所获得的材料首次被用作 N-杂环芳香化的异相光催化剂。使用活性最高的材料 CTF-Pyr(由具有光活性的和三嗪分子组成),可以获得多种吡啶、二氢喹啉-5-酮、四氢吖啶-1,8-二酮和吡唑,收率极高(70-99%)。此外,这些反应都是在非常温和的条件下,利用空气在室温下进行的,突出了这些材料作为绿色转化催化剂的潜力。
