Synthesis and characterization of amino glucose-functionalized silica-coated NiFe2O4 nanoparticles: A heterogeneous, new and magnetically separable catalyst for the solvent-free synthesis of 2,4,5-trisubstituted imidazoles, benzo[d]imidazoles, benzo[d]oxazoles and azo-linked benzo[d]oxazoles

Amino glucose-functionalized silica-coated NiFe2O4 nanoparticles (NiFe2O4@SiO2@amino glucose) were chemically synthesized and characterized by transmission electron microscope (TEM), X-ray diffraction (XRD), thermal gravimetric analysis (TGA), energy dispersive X-ray analysis (EDX), vibrating sample magnetometer (VSM), Zetasizer and Fourier transform infrared spectroscopy (FT-IR) instruments. NiFe2O4@SiO2@amino glucose supply an environmentally friendly procedure for the synthesis of 2,4,5-trisubstituted imidazoles through one-pot multicomponent condensation of benzil or benzoin, ammonium acetate with aryl aldehydes and for the synthesis of benzoxazoles using condensation reaction of 2-aminophenol with aryl aldehydes under solvent free condition. In the other study, this synthesized magnetically reusable catalyst was introduced as a new avenue for the synthesis of benzofdlimidazoles using the reaction between aryl aldehydes and 1,2-diaminobenzene. These compounds were obtained in high yields and short reaction times. The catalyst could be easily recovered and reused for five cycles with almost consistent activity. Synthesized compounds were characterized by their physical constant, comparison with authentic samples, FT-IR, H-1 NMR, C-13 NMR spectroscopy and elemental analysis. (C) 2018 Elsevier B.V.

Expanding the chemical space: Discovery of new anticancer3-arylbenzofuranderivatives

A new chemical space was generated via C-2-functionalization of 3-arylbenzofurans. Mannich reaction of 3-arylbenzofurans with secondary amines and formaldehyde allowed for installation of aminomethyl unit at C(2)position of benzofurans. A formyl group at C(2)site introduced as a result of Vilsmeier-Haack formylation of 3-arylbenzofurans was employed as a reacting partner for three-component Kabachnik-Fields reaction with various amines and triethyl phosphite to give a wide variety of aminomethylphosphonates. Furthermore, several benzo[d]oxazoles and pyrrolo[1,2-a]quinoxalines were prepared by using the formyl group. Biological screening of the synthesized compounds revealed that the benzofuran bearing a pyrrolo[1,2-a]quinoxaline moiety (5b) most potently inhibited the viability of human blood cancer cells, but not solid tumor cells. Caspase activity assay, analysis of Annexin V-positive cells, and Western blot analysis indicated that5b-induced death of human lymphoma U937 cells could result from its potential to induce the caspase-dependent apoptotic death of blood cancer cells with inhibition of ERK activation.

Tuning the heat resistance properties of polyimides by intermolecular interaction strengthening for flexible substrate application

Intrinsic polyimides (PIs) with high glass transition temperature (T-g), excellent thermal stability, and favorable mechanical properties have been in great demand in recent years with the rapid development of flexible displays. In this work, an interchain-interaction strengthener has been introduced to obtain PIs with improved thermal resistance and stability. Benzimidazole-based diamines imparting rigidity, conjugation, crosslinking, and especially hydrogen bonding have been incorporated into benzoxazole-polyimide. Frequency shifts in the IR bands spectra of C=O and N-H bonds were indicative of strong hydrogen bonding in benzimidazole-incorporating PIs, resulting in an increase in T-g from 333 degrees C to 442 degrees C. Furthermore, because of more extensive hydrogen bonding, PIs containing bis-benzimidazole units exhibited much higher crystallinity and T-g than those containing mono-benzimidazole units. The 5% weight loss temperature (T-d(5)) was above 550 degrees C because of the rigidity of the conjugated structure and the tightly packed state of the polymer chains. T-g and T-d(5) of PIs annealed in air were higher than those of samples annealed in vacuo, whereas the opposite trend was seen in crystallinity and mechanical properties. Finally, we delineated the effects of intermolecular interaction strengthener and annealing atmosphere on the properties of PIs, which may be helpful for the future design of flexible PI substrates.

Fluorescent Porous Silica Microspheres for Highly and Selectively Detecting Hg2+ and Pb2+ Ions and Imaging in Living Cells

In this work, SiO2 microspheres were first prepared by a conventional Stober method and then etched by NaOH solution to obtain porous ones. By tuning the degree of etching, specific surface area of SiO2 microspheres could be controlled. Then, small fluorescent molecules are synthesized and incorporated onto the surface and/or pores of the SiO2 via layer-by-layer reaction to obtain fluorescent microspheres, namely, SiO2-NH2-BODIPY (SiNBB), SiO2-NH2-BODIPY-indole-benzothiazole (SiNBIT), and SiO2-NH2-BODIPY-indole-benzoxazole (SiNBIO). The as-prepared microspheres SiNBB exhibit highly sensitive and selective recognition ability for Hg2+ and Pb2+. When SiNBB encounters Hg2+ and Pb2+, the fluorescence intensity of SiNBB is increased up to fivefold. SiNBIT and SiNBIO are solely sensitive to Hg2+, and both have a single high sensitivity to recognize Hg2+. The adsorption efficiency of Hg2+ by the three fluorescent microspheres SiNBB, SiNBIT, and SiNBIO reached 2.91, 0.99, and 0.98 g/g of microspheres, respectively. Experimental results of A549 cells and zebrafish indicate that the fluorescent microspheres are permeable to cell membranes and organisms. The distribution of Hg2+ in the brain of zebrafish was obtained by the fluorescence confocal imaging technique, and Hg2+ was successfully detected in A549 cells and zebrafish.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 405-50-5, you can contact me at any time and look forward to more communication. Computed Properties of C8H7FO2.
