    Improving the Potency of N-Aryl-2,5-dimethylpyrroles against Multidrug-Resistant and Intracellular Mycobacteria
    摘要:
    A series of N-phenyl-2,5-dimethylpyrrole derivatives, designed as hybrids of the antitubercular agents BM212 and SQ109, have been synthesized and evaluated against susceptible and drug-resistant mycobacteria strains. Compound 5d, bearing a cyclohexylmethylene side chain, showed high potency against M. tuberculosis including MDR-TB strains at submicromolar concentrations. The new compound shows bacteriostatic activity and low toxicity and proved to be effective against intracellular mycobacteria too, showing an activity profile similar to isoniazid.

    抗坏血酸可用作可回收的有机催化剂,通过己烷-2,5-二酮与各种单胺和二胺的 Paal-Knorr 缩合制备吡咯。反应顺利进行,在无溶剂条件下以中等至优异的产率提供所需产物。此外,对二胺反应物的研究表明,负载催化剂的量和底物的空间或电子性质是选择性形成相应的双吡咯或单吡咯的主要因素。-吡咯产品。采用密度泛函理论方法可以更好地理解抗坏血酸在此反应中的催化机理。优化计算指出抗坏血酸分子结构中存在3个可能的双功能氢键供体位点和1个氢键受体位点。尽管研究了所有四种可能的配合物,但抗坏血酸和己烷-2,5-二酮的羰基之间的两个双齿氢键配合物(平均氢键距离〜1.8-1.9 Å)是最稳定的配合物。配合物的MEP图和NBO分析与获得的自由能一致。此外,HOMO-LUMO能隙值的降低支持催化己烷-2,5-二酮对苯胺的化学反应活性的增加。 图形概要 抗坏血酸可用作可回收的双功能氢键有机催化剂,通过己烷-2,5-二酮与各种单胺和二胺的

  • Crystalline salicylic acid as an efficient catalyst for ultrafast Paal–Knorr pyrrole synthesis under microwave induction

    the viability of a wide range of crystalline aromatic and aliphatic carboxylic acids as organocatalysts has been investigated for solvent-free Paal–Knorr pyrrole synthesis under microwave activation. Among these potential catalysts, crystalline salicylic acid proved to be a remarkable catalyst because its efficiency remained high even under low microwave power irradiation or a shorter reaction time
    摘要 在这项研究中,已经研究了微波活化下无溶剂的Paal-Knorr吡咯合成中各种结晶性芳族和脂肪族羧酸作为有机催化剂的可行性。在这些潜在的催化剂中,结晶水杨酸被证明是出色的催化剂,因为即使在低微波功率辐照下或模型反应的反应时间较短的情况下,其效率仍然很高。水杨酸出色的催化活性使Paal–Knorr环缩合的周转频率高达1472 h -1,这在无金属均相催化的情况下是独一无二的。这种有机催化剂的吸引人的特点是它有助于超快速的吡咯合成,并且没有金属污染的风险。 图形摘要 概要:引入了一种绿色快速的方法,该方法通过水杨酸作为催化剂(固态)与微波的组合来合成2,5-二甲基吡咯。

    In this study, common naturally occurring organic acids, namely oxalic, malonic, succinic, tartaric and citric acid (as safe, inexpensive, and biodegradable organocatalysts), have been employed for Paal–Knorr pyrrole synthesis. The organocatalyzed reaction proved to be effective in ethanol at 60 °C. However, the reaction rate is mainly dominated by the nature and position of functional groups on the
    在这项研究中,常见的天然有机酸,即草酸、丙二酸、琥珀酸、酒石酸和柠檬酸(作为安全、廉价和可生物降解的有机催化剂)已被用于 Paal-Knorr 吡咯合成。证明有机催化反应在 60 °C 下在乙醇中是有效的。然而,反应速率主要取决于官能团在底物芳环上的性质和位置。这种无金属工艺可以容忍一系列官能团,应该被视为制药行业的一项资产,因为在吡咯支架的合成过程中不会发生金属污染。

  • Catalytic activity of the nanoporous MCM-41 surface for the Paal–Knorr pyrrole cyclocondensation
    作者:Kioumars Aghapoor、Mostafa M. Amini、Khosrow Jadidi、Farshid Mohsenzadeh、Hossein Reza Darabi

    Abstract

    The investigation of different oxide surfaces revealed that nanoporous silica (MCM-41) had the best catalytic activity for Paal–Knorr pyrrole synthesis. Despite the same composition, MCM-41 proved to be more effective than SiO2 itself, probably due to a significantly higher surface area of the SiO2 nanopores. The important features of this “clean” solvent-free protocol are the ease of recovery and the reuse of the catalyst for several cycles, operational simplicity, and easy product isolation and purification.
