Efficient copper-catalyzed tandem oxidative iodination and alkyne-azide cycloaddition in the presence of glycine-type ligands

Tandem oxidative iodination and alkyne-azide cycloaddition reaction has provided one of the most widely used methods for preparation of 5-iodo-1,2,3-triazoles. However, stoichiometric copper salts are involved in this type of reaction in order to enhance the reaction effectiveness, which caused some problems related to toxic metal contaminations and less sustainability. In this paper, we described that a copper-catalyzed (10 mol%) tandem oxidative iodination and alkyne-azide cycloaddition could be completed in the presence of the newly-found glycine-type ligands with low-cost Nal as the iodine resource. In the novel reaction system, a wide range of terminal alkyne, organic azide and inexpensive iodide could react effectively in one pot to give structurally diverse 5-iodo-1,4-subsitutied 1,2,3-triazoles. Natural product derivatives and alkynyl pyridines that hardly react under traditional conditions could also be transferred smoothly to the target products for the first time. (C) 2020 Elsevier Ltd.

Rheological non-isothermal mechanistic investigation on the curing of glycidyl azide polymer with solid nanofillers

The effects of ammonium perchlorate (AP) and graphene oxide (GO) on the curing of glycidyl azide polymer (GAP) were investigated. The rheological parameters of GAP crosslinked by bispropargyl succinate (BPS) were investigated by rheometry instrument. The curing kinetics by the differential isoconversional method revealed that AP (1 wt%) increased the apparent activation energy from 72.98 to 76.41 kJ mol(-1). However, the presence of GO (0.1 wt%) catalyzed the curing of GAP/triazole by decreasing the apparent activation energy to 62.86 kJ mol(-1). The physical models revealed that the addition of GO changed the cure mechanism of GAP/BPS as it acted as new nucleation sites. The Fourier-transform infrared (FTIR) and X-ray photoelectron (XPS) results also showed that chemical groups on the surface of GO reacted with the hydroxyl groups of GAP, which changed the curing mechanism of GAP/BPS and improved the tension strength of the propellant by 104%.

Effect of Nitro Derivatives of 1,2,4-Triazole on the Radiation-Induced Oxidation of Ethanol

The effect of 1,2,4-triazole and its nitro derivatives on the formation of final molecular products of radiation-induced transformations of oxygen-saturated ethanol has been studied. It has been found that the test compounds are almost not decomposed in the course of radiolysis, whereas they insignificantly decrease or do not affect the radiation-chemical yields of H2O2 and acetaldehyde. The experimental data indicate that the nitro derivatives of 1,2,4-triazole cannot compete with oxygen for alpha-hydroxyethyl radicals, and they do not interact with oxygen-centered radicals formed in the system. The reaction rate constant of the oxidation of alpha-hydroxyethyl radicals by the nitro derivatives of 1,2,4-triazole was found to be k <= 4.6 x 10(9) L mol(-1) s(-1) by calculation using the method of competing reactions. The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant.

N,N-Dialkylhydrazones as Versatile Umpolung Reagents in Enantioselective Anion-Binding Catalysis

An enantioselective anion-binding organocatalytic approach with versatile N,N-dialkylhydrazones (DAHs) as polarity-reversed (umpolung) nucleophiles is presented. For the application of this concept, a highly ordered hydrogen-bond (HB) network between a carefully selected CF3-substituted triazole-based multidentate HB-donor catalyst, the ionic substrate and the hydrazone in a supramolecular chiral ion-pair complex was envisioned. The formation of such a network was further supported by both experimental and computational studies, which showed the crucial role of the anion as a template unit. The asymmetric Reissert-type reaction of quinolines as a model test reaction chemoselectively delivered highly enantiomerically enriched hydrazones (up 95:5 e.r.) that could be further derivatized to value-added compounds with up to three stereocenters.

Solvothermal preparation of luminescent zinc(II) and cadmium(II) coordination complexes based on the new bi-functional building block and photo-luminescent sensing for Cu2+, Al3+ and L-lysine

In industry, over usage of Cu2+ and Al3+ will lead to toxic wastewater, which further to give serious pollution for the environment. On the other hand, L-lysine can enhance serotonin release in the amygdala, with subsequent changes in psychobehavioral responses to stress. Therefore it is the urgent problem to design a method for detecting the amount of Cu2+, Al3+, and L-lysine. In this work, through the solvothermal synthesis method, two new coordination complexes based on the new bifunctional building block 4′-(1H-1,2,4-triazole-1-yl)- [1,1′-biphenyl]-4-carboxylic acid (HL) have been synthesized, namely, [Zn(L)(2)center dot 4H(2)O] (complex 1) and [Cd(L)(2)center dot 4H(2)O] (complex 2). X-ray single-crystal diffractometer was used to analyze its structure, powder X-ray diffraction (PXRD) patterns confirmed that 1 and 2 powder’s purity and 1 can keep stable during the detection process of Cu2+, Al3+, and L-lysine, respectively. Elemental analysis, thermogravimetric analysis, infrared analysis, ultraviolet analysis and fluorescent spectrum have been used to characterize these complexes. The photo-luminescent test showed that 1 can accurately recognize Al3+ and Cu2+ among various cations. On the other hand, 1 can distinguish L-lysine among amino acid molecules. Therefore, 1 can be utilized as a multifunctional fluorescent probe for Al3+ (K-sv = 1.5570 x 10(4) [M](-1)), Cu2+ (K-sv = 1.4948 x 10(4) [M](-1)) and L-lysine (K-sv = 4.9118 x 10(4) [M](-1)) with low detection limits (17.5 mu M, 18.2 mu M, 5.6 mu M) respectively.

Synthesis and Structure of Nido-Carboranyl Azide and Its Click Reactions

Novel zwitter-ionic nido-carboranyl azide 9-N-3(CH2)(3)Me2N-nido-7,8-C2B9H11 was prepared by the reaction of 9-Cl(CH2)(3)Me2N-nido-7,8-C2B9H11 with NaN3. The solid-state molecular structure of nido-carboranyl azide was determined by single-crystal X-ray diffraction. 9-N-3(CH2)(3)Me2N-nido-7,8-C2B9H11 was used for the copper(I)-catalyzed azide-alkyne cycloaddition with phenylacetylene, alkynyl-3 beta-cholesterol and cobalt/iron bis(dicarbollide) terminal alkynes to form the target 1,2,3-triazoles. The nido-carborane-cholesterol conjugate 9-3 beta-Chol-O(CH2)C-CH-N-3(CH2)(3)Me2N-nido-7,8-C2B9H11 with charge-compensated group in a linker can be used as a precursor for preparation of liposomes for Boron Neutron Capture Therapy (BNCT). A series of novel zwitter-ionic boron-enriched cluster compounds bearing a 1,2,3-triazol-metallacarborane-carborane conjugated system was synthesized. Prepared conjugates contain a large amount of boron atom in the biomolecule and potentially can be used for BNCT.

Dual-functionalized ZIF-8 as an efficient acid-base bifunctional catalyst for the one-pot tandem reaction

An acid-base bifunctional zeolitic imidazolate framework catalyst (ZIF8-A61-SO3H) with amine and sulfonic acid groups was successfully prepared through simple two step post-synthetic modification: preparation of aminefunctionalized ZIF-8 with amine contents of 61% (ZIF8-A61) by the ligand exchange of 2-mIM with 3-amino1,2,4-triazole (Atz), followed by the sulfonic acid functionalization by the ring-opening reaction of 1,3-propanesultone with -NH2 groups in ZIF8-A61. Amine-functionalized ZIF8-A materials with difference amine contents (15%, 34%, and 61%, respectively) were also prepared by controlling the synthesis time. All obtained ZIF catalysts evaluated as a heterogeneous catalyst for one-pot deacetalization-Knoevenagel condensation tandem reaction. Compared with ZIF-8 and amine-functionalized ZIF-8 catalysts, ZIF8-A61-SO3H catalyst showed good catalytic performance with 100% conversion of the reactant and 98% selectivity of the final Knoevenagel product. An enhanced catalytic activity can be attributed to the co-existence of site-isolated acid-base groups on the ZIF8-A61-SO3H catalyst in close proximity. The heterogeneous nature of the catalytic system was confirmed by a hot-filtering test and the catalyst also exhibited reusable in the five repeated cycles. A plausible catalytic mechanism of deacetalization-Knoevenagel condensation reaction over ZIF8-A61-SO3H was also proposed.

Gestational exposure to tebuconazole affects the development of rat fetal Leydig cells

Tebuconazole is a triazole fungicide, used in agriculture to treat phytopathogenic fungi, and as a biocide, has been reported to be related to reproductive and developmental toxicity. The purpose of this study was to investigate the effect of tebuconazole exposure on rat fetal Leydig cells and fetal testis during pregnancy. Pregnant Sprague-Dawley rats were randomly divided into 4 groups, daily gavaged with corn oil (as a control), 25, 50, and 100 mg/kg body weight tebuconazole for 10 days (from the 12th day of pregnancy). Tebuconazole increased fetal serum testosterone and progesterone levels at a dose of 100 mg/kg. Exposure to 100 mg/kg tebuconazole significantly caused an increase in the number of fetal Leydig cells per testis without inducing cell aggregation. Tebuconazole up-regulated the expression of Star, Cyp11a1, Hsd17b3, and Fshr and their proteins. Further investigation found that tebuconazole caused increased phosphorylation of AKT1, ERK1/2, and mTOR, the level of BCL2, as well as the decrease of Beclinl, LC3B, and BAX, which may contribute to the fetal Leydig cell autophagy and proliferation. In conclusion, in utero exposure of tebuconazole causes the proliferation of fetal Leydig cells. (C) 2020 Elsevier Ltd. All rights reserved.

5-[Aryloxypyridyl (or nitrophenyl)]-4H-1,2,4-triazoles as novel flexible benzodiazepine analogues: Synthesis, receptor binding affinity and lipophilicity-dependent anti-seizure onset of action

A new series of 5-(2-aryloxy-4-nitrophenyl)-4H-1,2,4-triazoles and 5-(2-aryloxy-3-pyridyl)-4H-1,2,4-triazoles, possessing C-3 thio or alkylthio substituents, was synthesized and evaluated for their benzodiazepine receptor affinity and anti-seizure activity. These analogues revealed similar to significantly superior affinity to GABA(A)/benzodiazepine receptor complex (IC50 values of 0.04-4.1 nM), relative to diazepam as the reference drug (IC50 value of 2.4 nM). To determine the onset of anti-seizure activity, the time-dependent effectiveness of i.p. administration of compounds on pentylenetetrazole induced seizure threshold was studied and a very good relationship was observed between the lipophilicity (cLogP) and onset of action of studied analogues (r(2) = 0.964). The minimum effective dose of the compounds, determined at the time the analogues showed their highest activity, was demonstrated to be 0.025-0.1 mg/kg, relative to diazepam (0.025 mg/kg).
