Palladium-Catalyzed Sequential Heteroarylation/Acylation Reactions of lodobenzenes: Synthesis of Functionalized Benzo[d]oxazoles

We report an efficient palladium-catalyzed approach to the synthesis of benzoxazole derivatives via sequential heteroarylation/acylation reaction of iodobenzenes. Three readily available starting materials, iodobenzenes, anhydrides, and benzoxazoles, were smoothly coupled to form new C-C bonds at the ortho and ipso positions of the iodobenzenes to afford 2-heteroaryl-3-acylbenzene derivatives in good yields.

Synthesis and photoluminescence properties of different structural cuprous complexes regulated by benzoxazole ligands and halogen/pseudohalide ions

Reaction of 2-(2′-pyridyl) benzoxazole (2-PBO), 2-(4′-pyridyl)benzoxazole (4-PBO) and 2,2-(1,4-butanediyl)bis-1,3- benzoxazole (BBO) ligands with CuX (X = I, Br, SCN) afforded a binuclear copper(I) complex [Cu(2-PBO)(mu(2)-I)](2) (1) and three copper(I) coordination polymers [Cu-4(4-PBO)(4)(mu(3)-I)(4)](n) (2), {[Cu(4-PBO)(mu(3)-SCN)](2)}(n) (3) and {[Cu(BBO)(mu(2)-Br)](2)}(n) (4). The structural analysis revealed that the all copper(I) ions are four-coordinated and the geometric structure around the central copper(I) atom possessing slightly distorted tetrahedral geometry in complexes 1-4. Halogen or pseudohalide ions can not only act as counter anions, but also as ligands participation in coordination when the cuprous ion coordination sites are not saturated. Due to the different coordination modes of the benzoxazole ligands, in order to satisfy the tetra-coordination of cuprous ions, halogen or pseudohalide ions adopt mu(2) and/or mu(3)-bridging modes to synergistically complete coordination. Photoluminescence investigation show that complexes 1, 3 and 4 have two emission peaks, the high energy band peak is attributed to MLCT[d(10)(Cu)->pi*] and XMCT, the low energy band peak is caused by the (CC)-C-3 emission. This may be due to the presence of mu(2)-X (X = I, Br, S) in these complexes. However complex 2 only had one emission peak, which may be attributed to MLCT[d(10)(Cu)->pi*] and XMCT.

Synthesis of 2-((2-(Benzo[d]oxazol-2-yl)-2H-imidazol-4-yl)amino)-phenols from 2-((5H-1,2,3-Dithiazol-5-ylidene)amino)phenols through Unprecedented Formation of Imidazole Ring from Two Methanimino Groups

A new synthetic pathway to four substituted imidazoles from readily available 2-((4-aryl(thienyl)-5H-1,2,3-dithiazol-5-ylidene)amino)phenols has been developed. Benzo[d]oxazol-2-yl(aryl(thienyl))methanimines were proved as key intermediates in their synthesis. The formation of an imidazole ring from two methanimine derivatives likely includes the opening of one benzoxazole ring followed by ring closure by intermolecular nucleophilic attack of theN-methanimine atom to a carbon atom of another methanimine.

ESIPT clubbed azo dyes as deep red emitting fluorescent molecular rotors: Photophysical properties, pH study, viscosity sensitivity, and DFT studies

Monoazo colorants with separate inbuilt ESIPT core were selected to examine the influence of azo group para to the hydroxyl group of ESIPT core and their effect on their spectral properties. They displayed absorption maxima in the visible region around 480-493 nm. 6a exhibited a broad peak along with a bathochromic shift of 40/90 nm in the solvents DMF and DMSO due to the existence of tautomeric equilibrium. They are sensitive to basic pH with a bathochromic shift of 30 nm. They are emissive in the deep red region (565-640 nm) accompanied by a Stokes shift of 62-121 nm in DMF and DMSO. More interestingly, they showed viscosity sensitive enhancement in emission in DMF: PEG 400 system in the deep red region. 6(a-c) exhibit higher quantum yield in viscous solvent i.e. 99% PEG 400 compared to that of DMF. 6a and 6c show viscosity sensitive (x) value of 0.522 and 0.513 respectively. The enhancement of emission intensity in the viscous solvent is due to charge transfer which was elucidated by polarity plots i.e. Lippert-Malaga, Mac-Rae, Weller’s and Rettig’s plots. DFT and TDDFT methods were used to correlate the experimental findings.

Recent advances in polymeric membranes for CO2 capture

Membrane and membrane process have been considered as one of the most promising technologies for mitigating CO2 emissions from the use of fossil fuels. In this paper, recent advances in polymeric membranes for CO2 capture are reviewed in terms of material design and membrane formation. The selected polymeric materials are grouped based on their gas transport mechanisms, i.e., solution-diffusion and facilitated transport. The discussion of solution-diffusion membranes encompasses the recent efforts to shift the upper bound barrier, including the enhanced CO2 solubility in several rubbery polymers and novel methods to construct shape-persisting macromolecules with unprecedented sieving ability. The carrier-bearing facilitated transport membranes are categorized based on the specific CO2-carrier chemistry. Finally, opportunities and challenges in practical applications are also discussed, including post-combustion carbon capture (CO2/N-2), hydrogen purification (CO2/H-2), and natural gas sweetening (CO2/CH4).

Synthesis, p38 MAP kinase inhibition, anti-inflammatory activity, and molecular docking studies of 1,2,4-triazole-based benzothiazole-2-amines

Recent studies have demonstrated that inhibition of p38 MAP kinase could effectively inhibit pro-inflammatory cytokines including TNF- and interleukins. Thus, inhibition of this enzyme can prove greatly beneficial in the therapy of chronic inflammatory diseases. A new series of N-[3-(substituted-4H-1,2,4-triazol-4-yl)]-benzo[d]thiazol-2-amines (4a-n) were synthesized and subjected to in vitro evaluation for anti-inflammatory activity (BSA anti-denaturation assay) and p38 MAPK inhibition. Among the compounds selected for in vivo screening of anti-inflammatory activity (4b, 4c, 4f, 4g, 4j, 4m, and 4n), compound 4f was found to be the most active with an in vivo anti-inflammatory efficacy of 85.31% when compared to diclofenac sodium (83.68%). It was also found to have a low ulcerogenic risk and a protective effect on lipid peroxidation. The p38 MAP kinase inhibition of this compound (IC50=0.036 +/- 0.12M) was also found to be superior to the standard SB203580 (IC50=0.043 +/- 0.27M). Furthermore, the in silico binding mode of the compound on docking against p38 MAP kinase exemplified stronger interactions than those of SB203580.

Ternary Zn(II) Complexes of Fluorescent Zinc Probes Zinpyr-1 and Zinbo-5 with the Low Molecular Weight Component of Exchangeable Cellular Zinc Pool

The intracellular exchangeable Zn(II) is usually measured with synthetic fluorescent zinc sensors. 4′,5′-Bis[bis-(2-pyridylmethyeaminomethy1]-2′,7′-dichlorofluorescein (Zin-pyr-1) is a sensor containing the fluorescein platform and a duplicated chelating unit. Its advantages include brightness and a relatively high affinity for Zn(II), K-d = 0.7 nM. 2-(4, 5- Dimethoxy-2-hydroxypheny1)-4-(2-pyridylmethypaminomethyl- benzoxazole (Zinbo-5) is a member of a growing family of ratiometric synthetic Zn(II) probes, offering a possibility to determine Zn(II) concentration independently of the sensor concentration. Cells, however, contain high, millimolar or nearly millimolar concentrations of low molecular weight ligands (LMWLs) capable of binding Zn(II) ions. Previously, we demonstrated that such LMWLs can perturb the performance of some fluorescent zinc sensors by competition and formation of ternary Zn(sensor) (LMWL) complexes. Here we tested Zinpyr1 and Zinbo-5 in this respect. Despite structural differences, both sensors formed such ternary complexes. We determined their stability constants K-c(tern) and performed numerical simulations of Zn(II) distributions at physiological concentrations of selected LMWLs. Glutamic acid was found to provide the strongest ternary complexes with either of the studied sensors. Zn(Zinpyr1)(Glu) was an absolutely dominant Zn(II)/Zinpyr-1 species (more than 96% of the exchangeable Zn(II)), and Zn(Zinbo5)(Glu) was the most abundant one (more than 40%) in these simulations. Our results indicate that under cellular conditions these sensors are able to report Zn(II) complexed to LMWLs rather than free Zn2+ ions. On the other hand, the specific affinity of Zn(Zinpyr-1) and Zn(Zinbo-5) for Glu creates interesting opportunities for determining glutamic acid in biological samples.

Synthesis, Characterization and Antimicrobial Activity Study of Some New Substituted Benzoxazole Derivatives

This research included the preparation of 2-mercaptobenzoxazole (N1) by the reaction of ortho-aminophenol with carbon disulfide in an alcoholic potassium hydroxide solution. The 2-mercapto benzoxazole (N1) was then treated with hydrazine to obtain the 2-hydrazino benzoxazole (N2). A number of hydrazones (N3-N5) were prepared through the reaction of N2 with different benzaldehydes. The compound (N6) was also prepared whereby the ring closing of hydrazone (N3) using chloroacetylchloride, while the compound (N7) was prepared by treating 2-hydrazino benzoxazole with acetylacetone. When the compound (N1) was treated with formaldehyde, it afforded the compound (N8). Also, the N9 was obtained from the reaction of N1 with chloroacetic acid in the presence of alcoholic potassium hydroxide. The prepared compounds were characterized using physico-chemical and spectroscopic methods such as melting point, infrared spectroscopy (IR) and the proton nuclear magnetic resonance (H-1-NMR). Thereafter, some of the compounds were selected for in vitro antibacterial activity and one of these compounds showed an inhibition effect against gram positive only which is very important because it is considered as specific antibacterial drug.

Converting Unstable Imine-Linked Network into Stable Aromatic Benzoxazole-Linked One via Post-oxidative Cyclization

Efficiently converting unstable linkages into stable linkages is an important objective in the chemistry of covalent organic frameworks (COFs), because it enhances stability and preserves crystallinity. Here, an unstable imine-linked COF was converted into a stable aromatic benzoxazole-linked COF (BO-COF) via post-oxidative cyclization, based on chemistry used to form fused-aromatic ladder-like rigid-rod polymers. The structure of the porous BO-COF was confirmed by transmission electron microscopy, infrared and solid-state nuclear magnetic resonance spectroscopies, powder X-ray diffraction patterns, and nitrogen adsorption-desorption isotherms. The efficient post-treatment of an unstable reversible COF converted it into a stable irreversible COF, which had significantly improved thermal and chemical stabilities as well as high crystallinity. This strategy can be universally applied for the synthesis of stable fused-aromatic COFs, expanding their practical applications.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 112704-79-7, you can contact me at any time and look forward to more communication. COA of Formula: C7H4BrFO2.
