Abstract A series of bioactive bis(indolyl)methanes are synthesized by one-pot green reaction of indole with various substituted aldehydes by microwave irradiation under solvent free conditions. The antibacterialactivity against Staphylococcus aureus and anti-inflammatory activity of the synthesized bis(indolyl)methanes are evaluated in vitro and compared to standard drugs tetracycline and diclofenac

A new, facile, efficient, “green” and chemoselective procedure for the synthesis of indole derivatives has been developed with pulverization-activation method catalyzed by Bi(NO3)3·5H2O (PAMC- Bi(NO3)3·5H2O) through grinding of indoles with aldehydes or Michael acceptors in the presence of catalytic amounts of Bi(NO3)3·5H2O undersolvent-freeconditions.

synthesized in high yields by an electrophilic substitution reaction of indoles with carbonyl compounds under mild reaction conditions using two efficient heterogeneous catalysts, silicasupportedsodiumhydrogensulfate (NaHSO4⋅SiO2) and amberlyst-15. The second catalyst can be reused.
Bis-indolylation of aldehydes and ketones using silica-supported FeCl<sub>3</sub>: molecular docking studies of bisindoles by targeting SARS-CoV-2 main protease binding sites
We report herein an operationally simple, efficient and versatile procedure for the synthesis of bis-indolylmethanes via the reaction of indoles with aldehydes or ketones in the presence of silica-supported ferric chloride under grindstone conditions. The prepared supported catalyst was characterized by SEM and EDX spectroscopy. The present protocol has several advantages such as shorter reaction time
我们在此报道了一种操作简单、高效且通用的方法,用于在磨石条件下,在二氧化硅负载的氯化铁存在下,通过吲哚与醛或酮的反应来合成双吲哚基甲烷。通过SEM和EDX光谱对制备的负载型催化剂进行了表征。本方案具有反应时间短、产率高、反应过程中避免使用有害有机溶剂以及对多种官能团的耐受性等优点。使用合成的双吲哚进行了针对 SARS-CoV-2 主要蛋白酶(3CL pro或 M pro )酶结合位点的分子对接研究。我们的研究表明,一些合成的化合物有可能通过疏水性和氢键相互作用与活性位点的关键氨基酸残基相互作用,从而抑制 SARS-CoV-2 M前酶。

A novel, nonleachable hybrid of heteropoly acid and polyvinylpyrrolidone (or povidone) catalyzes the acetalization of aldehydes in methanol at roomtemperature followed by reaction with indole to give bis(indolyl)methanes (BIMs) and tris(indolyl)methanes (TIMs) in quantitative yields (90-97 %). The catalyst was shown by pyridine FTIR spectroscopy to possess Brønsted acidity, and the hybrid formation
新型,不可浸出的杂多酸和聚乙烯吡咯烷酮(或聚维酮)的杂物在室温下催化甲醇中醛的缩醛化,然后与吲哚反应生成定量的双(吲哚基)甲烷(BIM)和三(吲哚基)甲烷(TIM)收率(90-97%)。吡啶FTIR光谱表明该催化剂具有布朗斯台德酸度,并且通过XRD和31 P NMR研究证实了杂化物的形成。用几种类型的羰基和吲哚底物建立了吲哚的Friedel-Crafts烷基化以及BIM和TIM的串联合成,以定量得到相应的产物。该催化剂有效地再循环了三个连续的运行而没有失去其原始活性。
