The Nucleophilic Ring-opening of N-Benzylquinuclidinium Bromide
Axelsson, Oskar,Peters, Dan
, p. 461 - 463 (1997)
N-Benzylquinuclidinium bromide was ring opened by a series of heteronucleophiles, in the presence of cesium carbonate, to yield the corresponding N-benzyl-4-(2-hetero-ethyl)piperidines. The best yields were found with thiophenol (56%), phenol (55%), and benzimidazole (38%) as nucleophiles.
Ionic liquid as an efficient promoting medium for two-phase nucleophilic displacement reactions
Louren?o, Nuno M.T.,Afonso, Carlos A.M.
, p. 789 - 794 (2003)
The use of the room temperature ionic liquid (RTIL) 1-n-butyl-3-methylimidazolium hexafluorophosphate as an efficient catalyst and solvent for several representative nucleophilic substitution reactions under aqueous-RTIL phase transfer conditions was explored. Recycling and reuse of the reaction medium was demonstrated for the azide formation.

In this study, we have designed and synthesized 2-((5-acetyl-1-(phenyl)-4-methyl-1H-imidazol-2-yl)thio)-N-(4-((benzyl)oxy)phenyl) acetamide derivatives. Antimicrobial activities of all the imidazole derivatives have been examined against Gram-positive and Gram-negative bacteria and results showed that the conjugates have appreciable antibacterial activity. Besides, several analogous were evaluated for their in vitro antiresistant bacterial strains such as Extended-spectrum beta-lactamases (ESBL), Vancomycin-resistant Enterococcus (VRE), and Methicillin-resistant Staphylococcus aureus (MRSA). The SAR revealed that the 12l compound resulted in potency against all bacterial strains as well as ESBL, VRE, and MRSA strains. Lipinski's rule of five, and ADME studies were preformed for all the synthesized compounds with Staphylococcus aureus dihydropteroate synthase (saDHPS) protein (PDB ID: 6CLV) and were found standard drug-likeness properties of conjugates. Moreover, the binding mode of the ligands with the protein study has been examined by molecular docking and results are quite promising. Besides, all the analogous were tested for their in vitro antituberculosis, antimalarial, and antioxidant activity.

Paragraph 0020-0022, (2021/04/26)
The invention discloses an application of an iron (III) complex containing 1,3-di-tert-butyl imidazole cations in synthesis of aryl benzyl ether compounds, and particularly relates to a method for synthesizing corresponding aryl benzyl ether compounds by taking di-tert-butyl peroxide as an oxidizing agent and carrying out oxidative coupling reaction on phenolic compounds and toluene compounds. According to the method, the iron (III) complex is used as the catalyst for the first time, and oxidative coupling of the phenolic compound and the toluene compound is realized. The method is the first oxidative coupling reaction of phenolic compounds and benzyl C(sp3)-H bonds, and a new method is provided for synthesizing aryl benzyl ether compounds. Compared with an existing synthesis method, the method provided by the invention avoids using toxic and polluting halogenated hydrocarbon and strong base, has better atom economy, and conforms to the development concept of green synthetic chemistry.

Two series of tetrahydrocarbazole derivatives have been designed and synthesized based on ZG02, a promising candidate developed in our previous studies. The newly prepared compounds were screened for glucose consumption activity in HepG2 cell lines. Aza-tetrahydrocarbazole compound 12b showed the most potent hypoglycemic activity with a 45% increase in glucose consumption when compared to the solvent control, which had approximately 1.2-fold higher activity than the positive control compounds (metformin and ZG02). An investigation of the potential mechanism indicated that 12b may exhibit hypoglycemic activity via activation of the AMPK pathway. Metabolic stability assays revealed that 12b showed good stability profiles in both artificial gastrointestinal fluids and blood plasma from SD rats. An oral glucose tolerance test (OGTT) was performed and the results further confirmed that 12b was a potent hypoglycemic agent.
