The volatile compounds of peaches (Prunus persica L.) obtained from five cultivars (Chongyanghong, Y1; Ruiguang 19, Y2; Zaohongxia, Y3; Zaohong 2, Y4; and Wuyuehuo, Y5) were analyzed by gas chromatography-olfactometry (GC-O), gas chromatography-mass spectrometry (GC-MS) and GC-flame photometric detection (FPD). A total of 40 odor-active volatile compounds were observed in the GC-O experiments. Amongst those compounds, hexanal, (Z)-3-hexen-1-ol, (E)-2-hexenal, 3-mercaptohexanol, nonanal, -nonalactone, and -decalactone contributed greatly to aroma of peach. In addition, thirty-four quantified compounds were demonstrated as important odorants according to odor activity values (OAVs>1). Amongst these compounds, hexanal (OAV: 28-89), pentanal (OAV: 9-16), (E)-2-heptenal (OAV: 19-60), (E)-2-hexenal (OAV: 26-86), (E)-2-octenal (OAV: 10-42), (E)-2-nonenal (OAV: 8-94), -decalactone (OAV: 13-34), -decalactone (OAV: 2-19), (R)-(-)-linalool (OAV: 29-76) and phenyl acetaldehyde (OAV: 4-59) were the most powerful compounds in five varieties of peach.

Transition-metal-catalyzed cross-electrophile C(sp(2))-(sp(3)) coupling and C-H alkylation reactions represent two efficient methods for the incorporation of an alkyl group into aromatic rings. Herein, we report a Pd-catalyzed cascade cross-electrophile coupling and C-H alkylation reaction of 2-iodo-alkoxylarenes with alkyl chlorides. Methoxy and benzyloxy groups, which are ubiquitous functional groups and common protecting groups, were utilized as crucial mediators via primary or secondary C(sp(3))-H activation. The reaction provides an innovative and convenient access for the synthesis of alkylated phenol derivatives, which are widely found in bioactive compounds and organic functional materials.

As a widely used chemical material, bisphenol A (BPA) is often used to produce kinds of chemicals, which lead risk to the ecological environment and human health. Based on the multi-catalysis of the nano-ZnO and multi-effect (chemical and physical) formed in the dielectric barrier discharge plasma (DBDP) system, the synergistic elimination of the BPA in the DBDP system combined with nano-ZnO was evaluated. The obtained experimental results showed that the superior adding amount of the nano-ZnO was 50 mg/L and the synergistic system on the condition had the best effect for the BPA degradation (85.4%), which was 17% higher than that in the sole DBDP system. When O-2 was bubbled into the reaction system, the degradation efficiency of the BPA in the synergistic system reached 100% after 20 min treatment. Compared with the alkaline solution, the acidic and weakly acidic solution could obtain higher treatment efficiency. (OH)-O-center dot and O-2(-) had a vital role for the BPA elimination in the synergistic system. The intermediate products detected by LC-MS included 4-cumylphenol, 4-isopropenylphenol, 4-tert-butylphenol, propiophenone, 1-(4-hydroxyphenyl) ethanone, tert-butylbenzene, benzoquinone and 1, 4-dihydroxybenzene.

Hybrid Co3O4/MnO2 nanotube-based catalysts were prepared by a simple hydrothermal synthesis method. The physico-chemical properties of Co3O4/MnO2 catalyst were then studied by different characterization techniques, namely, SEM, TEM and HR-TEM, XRD, BET surface area, XPS and H-2-TPR. The hybrid catalyst showed superior catalytic performance toward benzyl alcohol oxidation than pure MnO2 nanotubes and Co3O4 nanoparticles. The uniform dispersion of Co3O4 nanoparticles, good redox behaviour, the variable oxidation states of manganese and cobalt (Mn3+/4+ or Co3+/2+) as well as the abundance of active surface oxygen species were responsible for such a high catalytic activity.

This work is generally focused on the synthesis of an efficient, reusable and novel heterogeneous Al2O3/CuI/PANI nanocatalyst, which has been well synthesized by a simple self-assembly approach where aniline is oxidized into PANI and aniline in the presence of KI also acts as a reductant. The nanocatalyst was well characterized by XRD, FTIR, SEM, EDX, TEM, BET and XPS techniques. In this study, the fabricated material was employed for the catalytic one-pot synthesis of 2-substituted benzimidazoles via condensation between o-phenylenediamine and aldehydes in ethanol as a green solvent. The present method is facile and offers several advantages such as high % yield, less reaction time, and no use of additive/bases. Also, the catalyst showed better values of green metrics including low E-factor: 0.17, high reaction mass efficiency: 85.34%, high carbon efficiency: 94%, and high process mass intensity: 1.17.

Lignin presents as a renewable aromatic resource for value-added chemical production. However, it remains challenging to cleavage C-C bonds in lignin under ambient conditions. Electrochemical oxidation as a renewable energy technology presents an attractive alternative to traditional processes. Herein, we report an efficient electrocatalytic strategy for C-alpha-C-beta bond cleavage of the beta-O-4 linkage in lignin model compounds at room temperature with platinum as the anode and tert-butyl hydroperoxides (t-BuOOH in water, 70% aq soln) as the oxidants, exhibiting high yields for the aromatic aldehydes and phenols. This electrocatalytic strategy is demonstrated to be highly selective for the transformation of a broad selection of lignin model dimers, polymeric compound, and even real lignin into the desired aromatic aldehydes. Mechanistic studies indicate that the reaction may proceed via a C-beta radical process involving a peroxide intermediate. This work opens up opportunities in electrocatalysis to selectively break C-alpha-C-beta bonds and transform lignin to valuable chemicals under ambient conditions by using renewable electricity.

Insects use their olfactory systems to obtain chemical information on mating partners, oviposition sites and food. The yellow fever mosquito Aedes aegypti, an important vector of human infectious diseases, shows strong preference for human blood meals. This study investigated the chemical basis of host detection by characterizing the neuronal responses of antenna! olfactory sensilla of female Ae. aegypti to 103 compounds from human skin emanations. The effect of blood feeding on the responses of olfactory sensilla to these odorants was examined as well. Sensilla SBTII, GP, and three functional subtypes of SST (SST1, SST2, and SST3) responded to most of the compounds tested. Olfactory receptor neurons (ORNs) ‘A’ and ‘B’ in the trichoid sensilla, either activated or inhibited, were involved in the odour coding process. Compounds from different chemical classes elicited responses with different temporal structures and different response patterns across the olfactory sensilla. Except for their increased responses to several odorants, blood-fed mosquitoes generally evoked reduced responses to specific aldehydes, alcohols, aliphatics/aromatics, ketones, and amines through the SST1, SST2, SBTI, SBTII and GP sensilla. The odorants eliciting diminished responses in female mosquitoes after blood feeding may be important in Ae. aegypti host-seeking activity and thus can be candidates for mosquito attractants in the process of this disease vector management.

I found the field of Chemistry very interesting.

Decomposition of bodies generates several types of polar volatile organic compounds (VOCs), whose types, patterns and ratios change during the various stages of decomposition and, therefore, their determination has huge potential to provide useful information to disclose events related to the time of death, or body surrounding environment. As sample preparation is a mandatory key-point in a method development, this research aims to develop a simple, accurate and rapid approach to study death-related polar VOCs based on headspace solid-phase microextraction (HS-SPME) combined with comprehensive two-dimensional gas chromatography-time of flight mass spectrometry (GC x GC-ToFMS) analysis. The performance of zwitterionic PIL-based fibers (containing a [VIm(+)C(9)COO(-)] monomer and a [(VIm)(2)Cl-2(2)+]-2Br(-) crosslinker), tailored for polar compounds, was evaluated for a set of 19 analytes associated with the unique odour created by decomposing bodies, and it was compared to the commercially-available fibers: divinylbenzene/carboxen/poly(dimethylsiloxane) – DVB/CAR/PDMS, poly(dimethylsiloxane)/divinylbenzene – PDMS/DVB and polyacrylate (PA). Fibers with absorptive-type mechanism, such as PA and PIL, showed the best results in the balance of the parameters studied, being able to detect analytes at ng level and providing a profile representative of the headspace composition, thus they may represent a useful tool to respond to current challenges in forensic taphonomy. The reproducibility (with relative standard deviation lower than 18%, depending on the analyte) and relative recoveries (higher than 99.1%) were similar and acceptable for both fibers. The zwitterionic PIL, with ca. 4 times smaller film thickness than PA, still has potential to have the best performance, supported by the efforts to obtain thicker sorbent coatings.

A series of 5-aryl-3-(4-oxo-2-phenylquinazolin-3(4H)-yl)-2-(pyridin-4-yl)thiazolidin-4-ones were synthesized and evaluated for their antibacterial and antifungal activities. Various spectral techniques e.g., IR, H-1 NMR, C-13 NMR and Mass spectrometry were used to determine structure of novel synthesized compounds. The title compounds showed good to excellent inhibition potency for respective Gram-positive bacterial strains and Gram-negative bacterial strains. These compounds exhibited a broad spectrum of inhibitory activity. Molecular docking studies against microbial DNA gyrase sub unit B could provide valuable insights into the binding affinity of these molecules and their plausible mechanism of antimicrobial action. Compounds 5a, 5d, 5f and 5h, 5i, 5j, 5o exhibited excellent activity against bacterial and fungal strains respectively.

In this study, a novel series of 1,2-disubstituted benzo[d]imidazoles was rationally designed as VEGFR-2 inhibitors targeting hepatocellular carcinoma. Our design strategy is two-fold; it aimed first at studying the effect of replacing the 5-methylfuryl moiety of the well-known antiangiogenic 2-furylbenzimidazoles with an isopropyl moiety on the VEGFR-2 inhibitory activity and the cytotoxic activity. Our second objective was to further optimize the structures of the benzimidazole derivatives through elongation of the side chains at their one-position for the design of more potent type II-like VEGFR-2 inhibitors. The designed 1,2-disubstituted benzimidazoles demonstrated potent cytotoxic activity against the HepG2 cell line, reaching IC50 = 1.98 mu M in comparison to sorafenib (IC50 = 10.99 mu M). In addition, the synthesized compounds revealed promising VEGFR-2 inhibitory activity in the HepG2 cell line, e.g., compounds 17a and 6 showed 82% and 80% inhibition, respectively, in comparison to sorafenib (% inhibition = 92%). Studying the effect of 17a on the HepG2 cell cycle demonstrated that 17a arrested the cell cycle at the G2/M phase and induced a dose-dependent apoptotic effect. Molecular docking studies of the synthesized 1,2-disubstituted benzimidazoles in the VEGFR-2 active site displayed their ability to accomplish the essential hydrogen bonding and hydrophobic interactions for optimum inhibitory activity.
