Thiazoles continue to attend in synthetic organic chemistry due to their wide applications in the development of corrosion inhibitors. This study presents synthesis and corrosion inhibition ability of three thiazoles)4-(2-aminothiazole-4-yl) phenol (ATP), 4-phenylthiazole-2-amine (PTA) and 4,4′-(thiobis(2-aminothiazole-5,4-diyl)) diphenol (TATD) on the copper surface, where TATD is a dimer form of ATP. The inhibition efficiencies were evaluated by potentiodynamic polarization, electrochemical impedance spectroscopy (EIS), atomic force microscopy (AFM) and scanning electron microscopy (SEM) in various concentrations of thiazoles containing 1 M HCl solution. Computational studies (density functional theory (DFT) and molecular dynamics (MD) simulation) were also performed. The corrosion inhibition efficiencies of these compounds at optimum concentration were about 90%, indicating that ATP, PTA and TATD could be employed as effective corrosion inhibitors. Comparing the corrosion inhibition efficiencies of monomer ATP and dimer form TATD of thiazole also indicated that dimerization of inhibitor did not cause better interaction with the copper surface and more efficiency. The adsorption of inhibitors could be successfully described by the Langmuir adsorption isotherm.

Chromatographic separation of the extracts of the Australian rainforest plant Ternstroemia cherryi led to the isolation of five undescribed barrigenol-like triterpenoids, ternstroenols A – E, from the fruits and three known ones from the leaves. Ternstroenols A – E represent a new form of structural diversity, being the first in its kind to incorporate a trans- 2, 4, 6- decatrienoyl moiety at C-22. The structures of the ternstroenols were assigned by detailed spectroscopic analysis, degradation and chemical derivatization. All compounds exhibited potent antiinflammatory activity in LPS and IFN-gamma activated RAW 264.7 macrophages, with IC50, values as low as 0.7 mu M. Despite the remarkable potency, high levels of unwanted cell growth inhibition was also observed, which prompted their cytotoxic evaluation in U87/U251 human glioblastoma cell lines.

Self-immolation (SI) is the key principle of ProTide nucleotide prodrugs such as remdesivir, which is currently used to treat COVID-19 patients. Developing novel tailor-made SI systems requires new analytical methods for the detection and monitoring of SI. We developed a robust method for SI analysis using novel phosphate-based SI linkers with NMR traceable cyclic intermediates to distinguish SI from alternative fragmentation pathways and to monitor cargo release in real time.

Arma chinensis is a predaceous insect species that can effectively suppress a wide range of agricultural and forest insect pests in the orders Lepidoptera, Coleoptera, Hymenoptera and Hemiptera in Northeast Asia. Adult A. chinensis males produce an aggregation-sex pheromone from dorsal abdominal glands and artificial aggregation-sex pheromone can attract adults of both sexes. The aggregation-sex pheromone consists of (E)-2-hexenal, (E)-2-hexen-1-ol, benzaldehyde and benzyl alcohol. Both antennae and proboscises of A. chinensis females and males responded to components from male dorsal abdominal gland extracts. (E)-2-hexenal and benzaldehyde elicited significantly higher EAG responses than those with (E)-2-hexen-1-ol and benzyl alcohol. Benzyl alcohol elicited the weakest EAG responses, although benzyl alcohol was the most abundant of the four major components in male dorsal abdominal gland extracts. A field bioassay using trap catches demonstrated that (E)-2-hexenal and benzyl alcohol were key components of the pheromone for catching conspecific adults. Single pheromone components were the least attractive to A. chinensis in the field.

The Name is 3-Hydroxybenzaldehyde. Through research, I have a further understanding and discovery of 100-83-4.

Twenty-six Biginelli adducts were synthesized through an ionic liquid-assisted synthesis with up to 92% yield. Sixteen of these Biginelli adducts were then assayed to determine their antiureolytic activity against purified urease from jack beans. The substances BA7-S, BA9-S and BA11-S were shown to be as efficient inhibitors as hydroxyurea, a positive control used in in vitro screening assay against urease. Fluorescence studies revealed that BA7-S, BA9-S, BA11-S and BA5-S possessed high binding constant values of 5.95, 6.72, 4.55, and 4.28 M-1, respectively, while BAS12-S, without substituents, showed a low value of log K-b = 2.16 M-1. In addition, in the most thermodynamically favorable BA5-S and BA7-S urease complexes, the corresponding Biginelli adducts were capable of interacting with the active site of urease through non-ionic interactions, such as hydrophobic interactions, or hydrogen and van der Waals interactions, respectively. In silico studies also supported that the BAs interact with the active site, confirming the fluorescence and kinetic assay studies, which clearly indicate that BA5-S and BA7-S are competitive inhibitors (K-i = 0.96 and 0.57 mM, respectively). In silico studies also showed that the substituents in the aromatic ring interact with Ni atoms to form a stable complex.

The preparation of mesoporous poly(ionic liquid)s (MPILs) is critically fundamental for the design of heterogeneous catalysts, whereas traditional methods are difficult to obtain these materials with both well-defined mesoporous structure and unique functionality. Here, HClO4-functionalized MPILs with well-defined mesoporous structure were successfully fabricated, in which the alkene-modified Fe3O4 nanoparticles as structural reinforcer play a vital role for mesoporous structure formation. The MPILs were characterized by N-2 adsorption/desorption, scanning electron microscope (SEM), transmission Electron Microscope (TEM), Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD), thermogravimetric analysis (TGA), and vibration sample magnetometry (VSM), and the results confirm that MPILs possess moderate surface area, well-defined mesoporosity, abundant active ionic centers, as well as efficient magnetic recovery. The resulting MPILs show excellent catalytic activity for condensation reaction and Knoevenagel condensation. The kinetic study reveals that the excellent catalytic activity of MPILs is attributed to the synergistic catalysis of mesoporous confinement effect and hydrogen proton from MPILs, albeit with mass transfer resistance produced by mesoporous channels. Further, the catalyst can be recovered using an external magnetic field and reused at least 10 times without a considerable decrease in its catalytic activity. Finally, alkene-modified Fe3O4 nanoparticle-mediated mesoporous construction promotes a textural engineering approach to the development of novel mesoporous materials for other applications.

A highly efficient B(C6F5)(3)-catalyzed tandem protonation/deuteration and reduction of in situ-formed enamines in the presence of water and pinacolborane was developed. Regioselective beta-deuteration of tertiary amines was achieved with high chemo- and regioselectivity. D2O was used as a readily available and cheap source of deuterium. Mechanistic studies indicated that B(C6F5)(3) could activate water to promote the protonation and reduction of enamines.

The current laboratory practices of organic synthesis are labor intensive, impose safety and environmental hazards, and hamper the implementation of artificial intelligence guided drug discovery. Using a combination of reagent design, hardware engineering, and a simple operating system we provide an instrument capable of executing complex organic reactions with prepacked capsules. The machine conducts coupling reactions and delivers the purified products with minimal user involvement. Two desirable reaction classes – the synthesis of saturated N-heterocycles and reductive amination – were implemented, along with multi-step sequences that provide drug-like organic molecules in a fully automated manner. We envision that this system will serve as a console for developers to provide synthetic methods as integrated, user-friendly packages for conducting organic synthesis in a safe and convenient fashion.

A regioselective radical C-H trifluoromethylation of aromatic compounds was developed using cyclodextrins (CDs) as additives. The C-H trifluoromethylation proceeded with high regioselectivity to afford the product in good yield, even on the gram scale. In the presence of CDs, some substrates underwent a single trifluoromethylation selectively, whereas mixtures of single- and double-trifluoromethylated products were formed in the absence of the CD. H-1 NMR experiments indicated that the regioselectivity was controlled by the inclusion of a substrate inside the CD cavity.
