Enones 1, are examples of available and attractive building block which already has the polyfluoroalkyl group in blocks skeleton and their functionalization is an actual and perspective approach for the synthesis of more functionalized molecules. This approach led us to new polyfluoroalkyl containing trioxabicyclo[3.3.1]nona-3,7-diene-4,8-dicarboxylates with four trifluoromethyl or two trifluoromethyl and two difluoromethyl groups in moderate yields (up to 68%). These compounds are perspective as synthetic intermediates for preparation of new polyfluoromethyl containing heterocycles as well as their interaction into macrocycles system like crown ethers.

A group of novel 1,4-bis(3,5-dialkyl-4H-1,2,4-triazol-4-yl)bencene and 5-aryltriaz- 1-en-1-yl-1-phenyl-1H-pyrazole-4-carbonitrile derivatives have been successfully synthesized and characterized by spectroscopic analyses. The triazenes were obtained in moderate yield by a coupling reaction between 5-aminopyrazol-4-carbonitrile and aryl diazonium chlorides, and their structures were confirmed by detecting the CN functional group in both IR and C-13 NMR spectra. Conversely, the novel 1,4-bis(3,5-dialkyl-4H-1,2,4-triazol-4-yl)benzene derivatives were obtained using a previously unreported and facile pathway starting with p-phenylenediamine with selected triethyl orthoalkylates and then hydrazine monohydrate, followed by refluxing in triethyl orthoalkylates. The structure of the methyl derivative was confirmed by X-ray analysis. The synthesized compounds were tested and evaluated as antimicrobial agents.

Selenophenolato hydrido iron(II) complexes 1-3 cis-[(H)(SeAr)Fe(PMe3)(4)] (Ar = C6H5 (1), p-MeOC6H4 (2) and o-MeC6H4 (3)) could catalyze transfer hydrogenation of aldehydes and ketones. Among the three complexes, catalyst 1 exhibited the highest catalytic activity. The catalytic reactions took place under very mild conditions, using isopropanol as solvent and hydrogen source, (BuONa)-Bu-t as base under 60-80 degrees C. This catalytic system has good tolerance for many functional groups, such as halides, C=C double bonds, nitro groups and cyano groups at the phenyl ring of the substrates.

Background: With respect to the increase in the average life expectancy, Alzheimer Disease (AD), the most common form of age-related dementia, has become a major threat to the population over the age of 65 during the past several decades. The majority of AD treatments are focused on cholinergic and amyloid hypotheses. Objective: In this study, three series of diphenyl-2-(2-(4-substitutedpiperazin-l-yl)ethyl)pyridazin-3(2H)-one derivatives were designed, synthesized and investigated for their ability to inhibit both cholinesterase enzymes and amyloid-beta aggregation. Method: The inhibitory activities of the synthesized compounds on AChE (from electric eel) and BChE (from equine serum) were determined by the modified Ellman’s method. The reported thioflavin T-based fluorometric assay was performed to investigate the effect of the selected compounds on the aggregation of A beta(1-42). The cytotoxic effect of the compounds (4g, 11g and 18g) was monitored in 3T3 cell lines to gain insight into therapeutic potential of the compounds by using MTT assay. The crystal structures of the AChE (1EVE) and BChE (1POI) enzymes were retrieved from the RCSB Protein Data Bank and Molecular Operating Environment (MOE) software was used for molecular docking of the ligands. Results: Among the tested compounds, 5,6-diphenyl derivative 18g was identified as the most potent and selective AChE inhibitor (IC50 = 1.75 mu M, Selectivity Index for AChE > 22.857). 4,6-Diphenyl derivative 11g showed the highest and the most selectivity for BChE (IC50= 4.97 mu M, SI for AChE < 0.124). Interestingly, 4,5-diphenyl derivative 4g presented dual cholinesterase inhibition (AChE IC50= 5.11 mu M; BChE IC50= 14.16 mu M, SI for AChE = 2.771). Conclusion: Based on biological activity results and low toxicity of the compounds, it can be said that diphenyl substituted pyridazinone core is a valuable scaffold. Especially, dual inhibitory potencies of 4,5-diphenylpyridazin-3(2H)-one core for the cholinesterase enzymes and A beta-aggregation makes this core a promising disease-modifying agent.

Efficient chemoselective transfer hydrogenation of the C=C bond of alpha,beta-unsaturated ketones has been developed, using the iridium complexes containing pyridine-imidazolidinyl ligands as catalysts and formic acid as a hydrogen source. In comparison with organic solvents or H2O as solvent, the mixed solvents of H2O and MeOH are critical for a high catalytic chemoselective transformation. This chemoselective transfer hydrogenation can be carried out in air, which is operationally simple, allowing a wide variety of alpha,beta-unsaturated substrates with different functional groups (electron-donating and electron-withdrawing substituents) leading to chemoselective transfer hydrogenation in excellent yields. The practical application of this protocol is demonstrated by a gram-scale transformation.

A facile, rapid one-step green strategy is established here to prepare the l-Histidine (His) capped silver nanoparticles (His-AgNPs) using microwave irradiation conditions performed for optimal duration of 5 min. For the prepared His-AgNPs have been characterized by X-ray powder diffraction spectroscopy (XRD), Fourier transform infrared spectroscopy (FTIR), high-resolution scanning electron microscopy (HR-SEM), Zeta potential measurements and high-resolution transmission electron microscopy (HR-TEM), Energy dispersive X-ray spectroscopy (EDX) and UV-Vis spectroscopy techniques also. The HR-SEM images have exposed that flake-like internal structure formation of His-AgNPs with sort nanometer-sized spherical shape morphology has attained. As well, studies prove that, the antibacterial activities of synthesized His-AgNPs had a significant performance against various G(+) and G(-) bacteria. Then, the photocatalytic actions of His-AgNPs seem to contain sustaining degradation of MB and MO aqueous dyes under visible light exposure. Overall, the 98% of cationic MB dye degraded within 40 min and 97% anionic MO dye degraded within 100 min of photocatalytic irradiation. The probable mechanism for the improved photocatalytic assets of the His-AgNPs is also discussed. Hence, this study validated a simple and economical approach to synthesize His-AgNPs that are potential candidates for various highly useful industrial and packaging applications.

A series of new mix aza- and thia-macrocyclic glycolipids (9, 111, 16 and 17) have been synthesized and their enantiomeric selectivity was studied. The synthesis of the macrocycles involved a simple protection of two hydroxyl groups of the glycolipids followed by building up the mix-heteroatom macrocyclic in simple sequences. The macrocycles and previously investigated analogues (la, n, a and 21) have been applied as phase transfer catalysts in the enantioselective Michael addition of 2-nitropropane to chalcone and showed good-to-excellent enantiomer excess (ee). Among the catalysts, the galactose aza-crown ether-based glycolipid 21 proved to be the most effective with 90% ee.
