Regioselective Synthesis of Novel [1,2,4]Triazolo[1,5-a]pyridine Derivatives

Herein we report the reaction of 2-(5-aryl-4H-1,2,4-triazol-3-yl)acetonitriles 1 a,b with appropriate Michael acceptors 2-4 to give novel [1,2,4]triazolo[1,5-a]pyridines 5-8, whose antioxidant properties have been investigated. A plausible reaction mechanism, supported by DFT calculations, has been proposed to explain the total observed regioselective formation of [1,2,4]triazolo[1,5-a]pyridine derivatives depending on the type of substituents on the Michael acceptor. Triazoles are well-known agents exhibiting antimicrobial,([1]) antitumor,([2]) anti-inflammatory,([3]) antihypertensive,([4]) anticonvulsant,([5]) antiviral([6]) and analgesic([7]) biological activities. On the other hand, pyridine is the key core of heterocyclic derivatives showing a variety of pharmacological properties.([8-12]) Several studies have revealed that a combination of different bioactive molecules, having different mechanisms of action, is a current strategy affording useful therapeutic agents.([13]) This is the case of the [1,2,4]triazolo[1,5-a] pyridine heterocyclic motif,([14]) present in a number of bioactive compounds,([15]) and largely used in materials chemistry.([16]) Accordingly, diverse synthetic methods have been described for the synthesis of differently substituted [1,2,4]triazolo[1,5-a]pyridines.([17-24]) Our group has recently reported the ultrasound-promoted facile and convenient one-pot procedure for the synthesis of novel [1,2,4]triazolo[1,5-a]pyridines in short reaction times and high yields, based on the reaction of 2-(5-aryl-4H-1,2,4-triazol-3-yl)acetonitriles, malononitrile (or ethyl cyanoacetate) and aromatic aldehydes, in absolute ethanol, in the presence of IRA-400.([25])

Hierarchical Spin-Crossover Cooperativity in Hybrid 1D Chains of Fe-II-1,2,4-Triazole Trimers Linked by [Au(CN)(2)](-) Bridges

Foremost, practical applications of spin-crossover (SCO) materials require control of the nature of the spin-state coupling. In existing SCO materials, there is a single, well-defined dimensionality relevant to the switching behavior. A new material, consisting of 1,2,4-triazole-based trimers coordinated into 1D chains by [Au(CN)(2)](-) and spaced by anions and exchangeable guests, underwent SCO defined by elastic coupling across multiple dimensional hierarchies. Detailed structural, vibrational, and theoretical studies conclusively confirmed that intra-trimer coupling was an order of magnitude greater than the intramolecular coupling, which was an order of magnitude greater than intermolecular coupling. As such, a clear hierarchy on the nature of elastic coupling in SCO materials was ascertained for the first time, which is a necessary step for the technological development of molecular switching materials.

Phenyl(triazolyl)carbene revisited: Unique role of triazolyl group on carbene chemistry

The chemistry of (1,4-diphenyl-1H-1,2,3-triazol-5-yl)(phenyl)carbenes (1T), originally reported by Smith et al., was reinvestigated by using modern spectroscopic methods as well as density functional theory (DFT) calculations, and the results were compared with that observed for analogous diphenylcarbene (1H) to clarify the role of triazole group in diarylcarbene chemistry. Product analysis indicated that 1T gave two intramolecular cyclization products (2 and 3) formed as a result of a formal attack of carbene on the phenyl rings at 1- and 4-positions of the triazole ring. The results were closely similar to that observed for 1H. The behaviors of triplet carbene (3)1T were directly monitored not only by electron spin resonance (ESR) and UV-Vis spectroscopic methods in rigid matrix at low temperature but also by laser flash photolysis in solution at room temperature and compared with those observed for (3)1H. Whereas the lifetime of (3)1T was some 2 orders of magnitude longer than that of (3)1H, the reactivity of (3)1T toward typical triplet trapping reagents was greater than that of (3)1H. In order to elucidate these rather conflicting observations, geometries and relative energies of carbenes 1T and 1H as well as species involved in the reactions leading to the final products were calculated by the DFT method. The results are interpreted as indicating that (3)1H decays by participating in the reaction of upper-lying (1)1H much more easily than (3)1T. The difference in the reactivity toward external trapping reagents is explicable by taking into account the difference in steric crowdedness around carbene center between the two.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 5117-12-4, you can contact me at any time and look forward to more communication. Name: 4-Acryloylmorpholine.

Zinc-based triazole metal complexes for efficient iodine adsorption in water

Radioactive iodine is extremely harmful to the environment, and it is of great significance to develop materials that efficiently remove iodine. We prepared two triazole metal complexes with simple method, denoted as Zn(tr)(OAc) and Zn(ttr)(OAc), which were used to adsorb iodine from aqueous solution. The properties and adsorption mechanism of the two materials were studied by different techniques including XRD, SEM, N-2 porosimetry at 77 K, FTIR, TGA, elemental analysis (EDS), and X-ray photoelectron spectroscopy (XPS). The results showed that both materials had good water and thermal stability. Pseudo-second-order kinetic model was better at describing the iodine adsorption kinetics onto the adsorbents. It was proved that chemical adsorption dominated, iodine mainly enriched on the materials in the form of I-3(-1). Zn(ttr)(OAc) had a higher adsorption capacity than Zn(tr)(OAc) due to the electron-donating group -NH2. The maximum adsorption capacity of the two materials for iodine reached 714.501 mg center dot g(-1) and 846.108 mg center dot g(-1) at 25 degrees C.

Regioselective synthesis and DFT computational studies of novel beta-hydroxy-1,4-disubstituted-1,2,3-triazole-based benzodiazepinediones using click cycloaddition reaction

Novel beta-hydroxy-1,4-disubstituted-1,2,3-triazole-based benzodiazepinedione derivatives were synthesized by a regioselective cascade reaction and were fully characterized by HRMS, FT-IR, H-1 NMR, and C-13 NMR measurements. The cascade reaction consists of the azidation of epoxides and the Huisgen [3+2] dipolar cycloaddition of the resulted beta-hydroxy azides with the N,N ‘-dipropargyl benzodiazepine to give the wished 1,2,3-triazole-based benzodiazepinedione derivatives. Good yields (60-85%), easily available and inexpensive starting materials, using water as a green solvent, and avoiding the handling of organic azides as they are generated in situ are the advantages of this method. Theoretical calculations were also conducted by the DFT method using the B3LYP functional and 6-31+G(d,p) basis set on structure to characterize structure 3a. For structural and electronic characterization, H-1 and C-13 chemical shifts were calculated by the computational method and interpreted. The DFT calculated data were in line with the experimental data.

An updated research of glycogen synthase kinase-3 beta inhibitors: a review

Glycogen synthase kinase-3 beta (GSK-3 beta) is a highly conserved multifunctional serine/threonine (Ser/Thr) protein kinase widely expressed in many tissues. GSK-3 beta inhibitors could be used in the treatment of human key diseases, such as cancer, Alzheimer’s disease, Parkinson’s disease, inflammation, type-II diabetes, and so on, due to the multi-role of GSK-3 beta in the hepatic glycolysis regulation, cell signaling pathways, and phosphorylation of various proteins. Recently, sets of diverse GSK-3 beta inhibitors have been prepared, and biologically evaluated in vitro and in vivo in different screening models. This review summarizes the latest developments in GSK-3 beta inhibitors unclosed from 2015 to 2019, including their structure-activity relationship and bioactivity studies.

Dual-Cationic Poly(ionic liquid)s Carrying 1,2,4-Triazolium and Imidazolium Moieties: Synthesis and Formation of a Single-Component Porous Membrane

Both imidazolium and 1,2,4-triazolium cations are important functional moieties widely incorporated as building blocks in poly(ionic liquid)s (PILs). In a classical model, a PIL usually contains either imidazolium or 1,2,4-triazolium in its repeating unit. Herein, via exploiting the slight reactivity difference of alkyl bromide with imidazole and 1,2,4-triazole at room temperature, we synthesized dual-cationic PIL homopolymers carrying both imidazolium and 1,2,4-triazolium moieties in the same repeating unit, that is, an asymmetrically dicationic unit. We investigated their fundamental properties, for example, thermal stability and solubility, as well as their unique function in forming supramolecular porous membranes via a water-initiated phase-separation and cross-linking process. With such knowledge, we identified a water-based fabricate strategy toward air-stable porous membranes from single-component Pits. This study will enrich the design tools and chemical structure library of PILs and expand their application spectrum.

Dynamics of Aspergillus fumigatus in Azole Fungicide-Containing Plant Waste in the Netherlands (2016-2017)

The treatment of patients suffering from Aspergillus diseases is hampered due to infections with Aspergillus fumigatus that are already resistant to medical azoles. Previous work has suggested that A. fumigatus likely gains resistance through environmental azole exposure in so-called hot spots. Here, we investigated A. fumigatus resistance dynamics over time at three sites at which farmers used azole fungicides for crop protection. Over 16 months, 114 samples were taken from stockpiles of decaying plant waste. A. fumigatus and azole fungicide residues were ubiquitously present in the plant waste. On average, 105 A. fumigatus CFU/g was recovered, of which roughly half were itraconazole and tebuconazole resistant. Similar tandem repeat-mediated resistance mechanisms were found in colonies cultured from plant waste as reported in clinical azole-resistant isolates. Our results show a consistent high burden of azole-resistant A. fumigatus in azole-containing plant waste and underscores the need to further investigate resistance-reducing interventions and transmission routes. IMPORTANCE Aspergillus fumigatus is consistently present independently on season at a high abundance in plant waste material throughout the sampling period. Our study confirmed that long-term storage sites of azole-containing decaying plant material can indeed be considered hot spots, which can sustain resistance development and maintenance in A. fumigatus. Roughly half of individual isolates were azole resistant and carried genetic mutations that are highly similar to those found in patients with azole-resistant invasive aspergillosis. Our work suggests that environmental sources of azole resistance in A. fumigatus may be important, underscoring the need for further studies on environment-to-patient transmission routes.

HOMO-controlled donor-acceptor contained polyimide for nonvolatile resistive memory device

Molecular orbital energy level plays a vital role in the storage performance of memory materials. Fixing LUMO levels, reasonable regulation of HOMO level can effectively optimize the memory behaviors of storage devices. Therefore, two triazole-based donor-acceptor contained polyimides (TZMPDA-6FDA, TZAPDA-6FDA) with similar LUMO levels but different HOMO levels are designed and synthesized by introducing the pendant groups with different electron-donating ability. The LUMO levels of TZMPDA-6FDA and TZAPDA-6FDA are-1.98 and 1.99 eV, respectively. In comparison with TZMPDA-6FDA, the HOMO level of TZAPDA-6FDA increased from 5.32 to -5.23 eV due to the stronger electron-donating ability of diethylamino group than methoxy group. The increased HOMO level can reduce the energy barriers for charge carriers injection and migration, and thus effectively decrease the threshold voltage of memory devices from -2.4 to-1.8 V. The high-lying HOMO levels can facilitate the intraand inter-molecular charge transfer, which benefit to optimize the performance of the memory device.
