All synthesized compounds exhibited enantiotropic smectic behavior and followed a typical transition curve. Thermal phase transitions were recorded using a polarizing optical microscope equipped with a heating stage. The structures of the synthesized compounds were confirmed based on 1H NMR and IR spectral analyses. The introduction of a methoxy (–OCH3) substitution at the ortho position in a phenyl ring with a terminal alkyl chain resulted in a lower Cr–Sm phase transition temperature and decreased thermal stability. The average onset of the smectic phase for 9a–9e was 55.6°C, whereas for 10a–10e, it was 84.2°C. Comparatively, the average thermal stability for the unsubstituted homologous series was 130.2°C, whereas for the methoxy-substituted homologous series, it was 83.4°C.","PeriodicalId":766,"journal":{"name":"Russian Journal of Organic Chemistry","volume":"60 1 supplement","pages":"S152 - S159"},"PeriodicalIF":0.8,"publicationDate":"2025-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142940950","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Molecular docking of some of the synthesized compounds showed good results. 1,3,4-Thiadiazole derivatives (1a, 1b) were prepared by a reaction of p-nitrobenzoic acid or p-toluic acid with thiosemicarbazide in the presence of POCl3. Alkylation of compounds 1a, 1b with allyl bromide produced N-allyl thiadiazoles 2a, 2b. Cyclization of the prepared p-substituted azidobenzene and alkyl azides with compounds 2a, 2b resulted in the corresponding 1,4-disubstituted triazoline derivatives 3a–3h and 4a–4d. Molecular docking studies with the target 6ul7 indicated favorable docking scores and binding interactions for the newly synthesized compounds, highlighting their potential as effective antimicrobial agents.","PeriodicalId":766,"journal":{"name":"Russian Journal of Organic Chemistry","volume":"60 1 supplement","pages":"S70 - S77"},"PeriodicalIF":0.8,"publicationDate":"2025-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142940954","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study reports an efficient and environmentally friendly method for synthesizing bis(indolyl)methanes via a one-pot reaction between indole and aromatic aldehydes using a nickel oxide/alumina nanocatalyst. The catalyst was prepared by co-precipitation of nickel nitrate hexahydrate and urea in the presence of γ-Al2O3, followed by calcination, and characterized using TEM and SEM techniques to confirm its nanoscale morphology. The reactions were performed in water as a solvent under reflux conditions, giving high product yields (up to 97%) within short reaction times (15 min). All the catalyst is inferior of the known CeO2 catalyst, it allows the use of water instead of chloroform as a solvent. The catalyst was successfully recycled up to five times without significant loss in efficiency, demonstrating its stability and reusability. Experimental methods included monitoring the reaction progress using thin-layer chromatography and product characterization by IR and NMR spectroscopy. The proposed method for the synthesis of bis(indolyl)methane derivatives offers advantages such as simple product separation, low catalyst consumption, and minimal purification losses, presenting a sustainable and effective approach for the synthesis of bis(indolyl)methanes.","PeriodicalId":766,"journal":{"name":"Russian Journal of Organic Chemistry","volume":"60 1 supplement","pages":"S147 - S151"},"PeriodicalIF":0.8,"publicationDate":"2025-01-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142940945","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
