Nickel-catalyzed reduction of (het)arenecarboxylic acids with hydrosilanes in the presence of dimethyl dicarbonate as the activator affords the corresponding aldehydes. The role of the activator is the conversion of the acids into their anhydrides undergoing C?O cleavage. The good yields were achieved in case of substrates bearing electron-donating and electron-neutral groups.

A class of aryne precursors, that is, 2-(trimethylsilyl)aryl 4-chlorobenzenesulfonates, has been developed through well-established synthetic routes, which allow the formation of arynes under relatively mild conditions. All the aryne precursors were obtained from phenols and 4-chlorobenzenesulfonyl chloride, an inexpensive and easy-to-handle reagent with relatively low toxicity, and subjected to nucleophilic addition reactions, providing addition products in yields of 24 to 92%, and to cycloaddition reactions, affording cycloadducts in yields up to 80%. This work provides interesting insights into the mechanisms of aryne generation. In addition, 2-(trimethylsilyl)phenyl 4-chlorobenzenesulfonate was successfully employed in the total synthesis of (+/-)-aporphine.

Background Triazole is an important heterocyclic moiety that occupies a unique position in heterocyclic chemistry, due to its large number of biological activities. It exists in two isomeric forms i.e. 1,2,4-triazole and 1,2,3-triazole and is used as core molecule for the design and synthesis of many medicinal compounds. 1,2,4-Triazole possess broad spectrum of therapeutically interesting drug candidates such as analgesic, antiseptic, antimicrobial, antioxidant, anti-urease, anti-inflammatory, diuretics, anticancer, anticonvulsant, antidiabetic and antimigraine agents. Methods The structures of all synthesized compounds were characterized by physicochemical properties and spectral means (IR and NMR). The synthesized compounds were evaluated for their in vitro antimicrobial activity against Gram-positive (B. subtilis), Gram-negative (P. aeruginosa and E. coli) bacterial and fungal (C. albicans and A. niger) strains by tube dilution method using ciprofloxacin, amoxicillin and fluconazole as standards. In-vitro antioxidant and anti-urease screening was done by DPPH assay and indophenol method, respectively. The in-vitro anticancer evaluation was carried out against MCF-7 and HCT116 cancer cell lines using 5-FU as standards. Results, discussion and conclusion The biological screening results reveal that the compounds T-5 (MICBS, EC = 24.7 mu M, MICPA, (CA) = 12.3 mu M) and T-17 (MICAN = 27.1 mu M) exhibited potent antimicrobial activity as comparable to standards ciprofloxacin, amoxicillin (MICCipro = 18.1 mu M, MICAmo = 17.1 mu M) and fluconazole (MICFlu = 20.4 mu M), respectively. The antioxidant evaluation showed that compounds T-2 (IC50 = 34.83 mu g/ml) and T-3 (IC50 = 34.38 mu g/ml) showed significant antioxidant activity and comparable to ascorbic acid (IC50 = 35.44 mu g/ml). Compounds T-3 (IC50 = 54.01 mu g/ml) was the most potent urease inhibitor amongst the synthesized compounds and compared to standard thiourea (IC50 = 54.25 mu g/ml). The most potent anticancer activity was shown by compounds T-2 (IC50 = 3.84 mu M) and T-7 (IC50 = 3.25 mu M) against HCT116 cell lines as compared to standard 5-FU (IC50 = 25.36 mu M).

Catalytic fast pyrolysis (CFP) biocrudes can comprise up to 30 wt % of oxygen content in compounds such as polyphenols, acids, carbonyls, and anhydrosugars and thus require upgrading by, e.g., hydrotreatment, to produce transport fuels. The chemical characterization of phenolic and acidic compounds in biocrudes is of great importance to optimize the CFP process. In this study, an analytical workflow is proposed for nontarget chemical fingerprinting analysis of CFP biocrudes using supercritical fluid chromatography high-resolution mass spectrometry (SFC-HRMS) with negative electrospray ionization (ESI-), followed by multivariate data analysis. The method was developed and tested on five biocrude samples from loblolly pine (Pinus taeda) with varying oxygen content (14.9-28.8 wt % wet basis) due to different CFP conditions. The pixel-based analysis displayed chemical variation between all samples. Twenty-four regions of interest were tentatively identified, including mono- and polyphenols, fatty acids, and methylated and methoxylated phenols. The identification workflow and MS/MS analysis were prioritized on the peaks with the highest relative concentration. The developed SFC-ESI–HRMS method shows high repeatability and analyzed oxygen-containing compounds with hydroxyl and/or carboxyl moieties in combination with other moieties of up to 400 Da.

A highly efficient and modular synthesis of nematode pheromone ascarosides was developed, which highlights a 4-step scalable synthesis of the common intermediate 10 in 23% yield from commercially available l-rhamnose by using orthoesterification/benzylation/orthoester rearrangement as the key step. Six diverse ascarosides were synthesized accordingly. Notably, biological investigations revealed that ascr#1 and ascr#18 treatment resulted in enhanced callose accumulation in Arabidopsis leaves. And ascr#18 also increased the expression of defense-related genes such as PR1, PDF1.2, LOX2 and AOS, which might contribute to the enhanced plant defense responses. This study not only allows a facile access to 1-O, 2-O, and 4-O substituted ascarosides, but also provides valuable insights into their biological activities in inducing plant defense response, as well as their mode of action.

A palladium-catalyzed domino method for the direct synthesis of carbamates and ureas has been developed by using readily available and economical starting materials (aryl halide, carbon monoxide, sodium azide, amines and alcohols) in a one-pot approach. The domino process underwent carbonylation, Curtius rearrangement, and nucleophilic addition. This protocol provides a step-economical and highly efficient reaction to access the wide range of valuable carbamates, symmetrical and unsymmetrical ureas with high yields under remarkable mild reaction conditions that are important factors in pharmaceutical science, biochemistry and agricultural industries. Furthermore, the magnetically recoverable nanocatalyst (Fe3O4@SiO2/Pd(II)) can be conveniently and swiftly recycled using external magnet and reused at least for seven times without noticeable loss of its catalytic activity.

Rubber process oils (RPOs) are generally incorporated to rubber compounds for improving processability and also state-of-mix in some circumstances, for example; in the formulations having relatively high filler content. The aim of this work is to prepare the modified soybean oil (MSO) via transesterification reaction of soybean oil (SO) with benzyl alcohol. The success of modification was evidenced by Fourier transform infrared spectroscopy and nuclear magnetic resonance spectroscopy (NMR). After modification, the new absorption peaks at 3020 cm(-1)and 750 cm(-1)corresponding to -CH stretching vibration and C-H out-of-plane of aromatic were observed.H-1-NMR result also shows the signal of proton in aromatic ring at 7.40-7.55 ppm confirming the presence of aromatic ring in SO. The prepared MSO was then used as rubber processing oil (RPO) in tread compound formulation, and its performance was compared with unmodified SO, distillate aromatic extract oil (DAE) and treated distillate aromatic extract oil (TDAE). The incorporation of RPOs demonstrated cure retardation with a minimal magnitude found in the MSO-filled system. However, the addition of RPOs decreased the mechanical properties, i.e., hardness, modulus, tensile strength and tear strength. Among the studied RPOs, SO showed the poorest performance in terms of rubber mechanical properties, whereas MSO gave the rubber vulcanizate with comparable mechanical properties to DAE and TDAE. Similar to DAE and TDAE, the addition of MSO resulted in the improved wet grip with the sacrifice of rolling resistance.
