Six benzoxazole-terminated mesogenic compounds with fluoro substituent at different positions were prepared and their properties investigated. The compounds give a high birefringence (Delta n similar to 0.45) and a large-dielectric anisotropy (Delta epsilon similar to 26), indicating a possible application in liquid-crystal mixture as a dopant to enhance performance of the host mixture. In accordance with conventional high Delta n liquid crystals containing triple carbon-carbon bonds, lateral fluoro substituents and terminal groups can alter the Delta n and Delta epsilon of benzoxazole-terminated liquid crystals. Meanwhile, some parameters such as dipole moment, polarisability, dihedral angles are calculated with density functional theory (DFT) methods to relate to the experimental Delta n and Delta epsilon. It is noted that the introduction of the benzoxazole unit is an effective method to enhance Delta n and Delta epsilon values of the rodlike molecule, this is ascribed to its pi-conjugated benzene-fused heterocycle and large dipole moment.

New kinds of heterocyclic mesogenic compounds containing benzoxazole, ethynyl, and laterally fluorinated phenyl groups, namely 2-[4-[2-[4-alkoxyphenyl]ethynyl]-2,3-difluorophenyl]benzoxazole derivatives (nPEDFPBx), are synthesized and evaluated. The compounds nPEDFPBx except nitro-substituted ones have enantiotropic nematic mesophases with mesophase ranges of 16-86 degrees C and 29-108 degrees C on heating and cooling, respectively. The results show that introduction of two lateral fluorine atoms into molecule results in enhanced nematic mesophase stability. Meanwhile, nPEDFPBx displays much higher birefringence (0.507-0.624) than common tolanebased liquid crystals, which is ascribed to its large pi-conjugated molecule composed of benzene, ethynyl, and benzoxazole mesogenic unit. The nPEDFPBx has a high potential to serve as a dopant for liquid crystal mixture. [GRAPHICS] .

New discoveries in chemical research and development in 2021. As an important bridge between the micro, chemistry is one of the main methods and means for humans to understand and transform the material world.

Benzoxazole and its derivatives have been widely studied in recent years due to their various biological properties. A previous study has demonstrated that K313 (1H-indole-2,3-dione 3-(1,3-benzoxazol-2-ylhydrazone)), a novel benzoxazole derivative, inhibits T cell proliferation to yield immunosuppressive effects. However, there are no related reports about its anti-inflammatory effects. In the present study, we investigated the anti-inflammatory properties and the underlying molecular mechanism of K313 in lipopolysaccharide (LPS)-induced RAW264.7 macrophages. K313 dose-dependently (5, 10, and 20M) inhibited LPS-stimulated nitric oxide (NO), interleukin (IL)-6, tumor necrosis factor (TNF)-, and 3-nitrotyrosine (3-NT) production and significantly decreased the gene transcription levels of inducible nitric oxide (iNOS), IL-6, and TNF-. In addition, the results showed that the inflammatory cytokines suppressed by K313 were not regulated by p65 NF-B, ERK1/2, AKT, or p38 MAPK. Instead, K313 increased phosphorylation of glycogen synthase kinase-3 beta (GSK-3) (Ser9) resulting in GSK-3 deactivation. Moreover, in LPS-stimulated RAW264.7 macrophages, K313 and lithium chloride (LiCl) had a synergistic effect on the anti-inflammatory response. These results indicated that K313 exhibited anti-inflammatory properties and revealed the potential mechanism. K313 can increase GSK-3 (Ser9) phosphorylation to decrease GSK-3 activation in LPS-induced RAW264.7 macrophages.

alpha-Substituted amines are present in a myriad of biologically active natural and synthetic products. With the objective of developing atom-economical reactions, a panel of synthetic methods allowing the direct functionalization of C(sp(3))-H bonds adjacent to the nitrogen atom have been developed. The field remains dominated by the sequence a-lithiation/addition on an electrophile even if the use of reactive organolithium reagents is not compatible with all functional groups. Over the past ten years, an increasing interest has been devoted to metal-catalyzed C-H-activation, some studies being specially dedicated to C(sp(3))-H bond activation. Notably, this approach has been envisioned to perform direct alpha-functionalization of amines. The aim of this article is to give an overview of synthetic methods for transition metal-catalyzed alpha-allcylation of amines by C(sp(3))-H bond activation. (C) 2018 Published by Elsevier Ltd.

Gout is a crystalline-related arthropathy caused by the deposition of monosodium urate (MSU). Acute gouty arthritis is the most common first symptom of gout. Studies have shown that NOD-like receptor protein 3 (NLRP3) inflammasome as pattern recognition receptors can be activated by uric acid crystallization, triggering immune inflammation and causing acute gouty arthritis symptoms. Currently, the treatment of gout mainly includes two basic methods: reducing uric acid and alleviating inflammation. In this paper, 22 novel benzoxazole and benzimidazole derivatives were synthesized from deoxybenzoin oxime derivatives. These compounds have good inhibitory effects on NLRP3 and XOD screened by our research group in the early stage. The inhibitory activities of XOD and NLRP3 and their derivatives were also screened. Notably, compound 9b is a multi-targeting inhibitor of NLRP3 and XOD with excellent potency in treating hyperuricemia and acute gouty arthritis.

Novel fluorescent dyes such as benzoxazole-boron complexes, bearing beta-ketoiminate ligands, have been synthesized and characterized with a focus on the influence of a substituent on the basic photophysical properties. H-1, B-11, C-13, N-15, and F-19 nuclear magnetic resonance (NMR) spectra of substituted 2-phenacylbenzoxazole difluoroboranes have been recorded and discussed. It is worth mentioning that a high correlation coefficient was found between N-15-NMR parameters and substituent constants. The photophysical properties of these new dyes have been investigated by fluorescence and ultraviolet-visible (UV-Vis) absorption spectroscopy. The geometry optimization, vibrational spectra, and the HOMO and LUMO energies were calculated based on density functional theory with the use of the B3LYP functional and 6-311++G(d,p) basis set.

A Pd-catalyzed aerobic approach to access C4-aryl benzoxazoles by tandem C-H ortho-arylation and acid-mediated annulation of 2-amidophenol has been presented. The directing potential of the -NHCOR group over the -OH group was exploited for selective arylation adjacent to the amide group. Deuterium labeling experiments suggest that palladation predominantly occurs adjacent to the -NHCOR group and is the key step during benzoxazole formation. One-pot hydrolysis of the resulting C4-arylated benzoxazole was also accomplished to access structurally challenging 3-aryl aminophenols for further applications.
