The degradation of organic contaminants in aquatic systems has raised immense attention worldwide, and the second-order rate constant (k(SO4)(-)) of water pollutants oxidized by sulfate radical anion is an important index for assessing the degradation efficiency of organics. Herein, a new norm mathematical formula is defined. Based on this, four new descriptors are proposed and a QSPR model is developed for predicting k(SO4)(-) using 30 families of emerging organic pollutants in water. The statistical results fully prove that this model has good fitting effect and stability with R-2 of 0.8862, Q(LOO)(2) of 0.8466, and Q(5-fold)(2) of 0.8329, respectively. The validation results including cross validation, applicability domain analysis, and model comparison show that this model has good robustness, predictive performance, and reliability. These decent results indicate that the new norm mathematical formula is effective in calculating descriptors and the norm indexes have a great application for evaluating the transformation fate of organic pollutants by sulfate radical in aquatic systems.

Cooperative bimetallic catalysis is a fundamental approach in modern synthetic chemistry. We report bimetallic cooperative catalysis for the direct decarbonylative heteroarylation of ubiquitous carboxylic acids via acyl C-O/C-H coupling. This novel catalytic system exploits the cooperative action of a copper catalyst and a palladium catalyst in decarbonylation, which enables highly chemoselective synthesis of important heterobiaryl motifs through the coupling of carboxylic acids with heteroarenes in the absence of prefunctionalization or directing groups. This cooperative decarbonylative method uses common carboxylic acids and shows a remarkably broad substrate scope (>70 examples), including late-stage modification of pharmaceuticals and streamlined synthesis of bioactive agents. Extensive mechanistic and computational studies were conducted to gain insight into the mechanism of the reaction. The key step involves intersection of the two catalytic cycles via transmetallation of the copper-aryl species with the palladium(II) intermediate generated by oxidative addition/decarbonylation.

The firstN-bromosuccinimide (NBS)-promoted transition metal-free cross-dehydrogenative esterification of carboxylic acids with dimethyl sulfoxide (DMSO) has been disclosed for formal C-O formationviaPummerer-type rearrangement. These transformations employ readily available carboxylic acids as the nucleophile and DMSO as the sulfur-containing carbon source and solvent under mild conditions, affording valuable (methylsulfinyl)methyl esters with a broad substrate scope. Furthermore, the developed protocol provides an efficient and straightforward method for the preparation of deuterated (methylsulfinyl)methyl esters by use of deuterium-labelled DMSO as the reagent.

The direct preparation of ketones from carboxylate anions is greatly limited by the required use of organolithium reagents or activated acyl sources that need to be independently prepared. Herein, a specific magnesium amide additive is used to activate and control the addition of more tolerant Grignard reagents to carboxylate anions. This strategy enables the modular synthesis of ketones from CO2 and the preparation of isotopically labeled pharmaceutical building blocks in a single operation.

Selective tandem oxidative C-H olefination-azaMichael/aza-Wacker reaction of N-arylbenzamides is achieved by fine-tuning between base and additive to access valuable 3-oxoisoindolinyls and 3-oxoisoindolinylidenes, respectively. Careful optimization and control experiments provides a guiding principle in the design of a proposed catalytic cycle. The copper-iminium complex acting as a precursor for the binding of Ru catalyst was isolated and confirmed by X-ray diffraction. The versatility of this catalytic system has been demonstrated by the synthesis of biologically relevant molecules.

The molecular geometry observed for the compounds is predominantly distorted trigonal bipyramidal, the fact which was subsequently authenticated through X-ray analyses for (1-4). All the synthesized compounds have been bio-assayed for antileishmanial (Leishmania tropica KWH23) and Jack beans urease inhibitory activity, and human Lymphocytes were used to measure the general toxicity. Of these, (4) proved to be highly effective against the target species (Leishmania tropica KWH23), while being non-toxic towards the mammalian cells at levels below 0.74 mu gmL(-1), making it highly promising drug candidate. The high activities for (2, 4, and 6) against Jack beans Urease as compared to the reference standard demonstrate their significance in searching of therapeutic agents in future programs. The significant binding score of (2&4) against H. pylori in molecular docking studies further revealed their importance in future drug discovery processes.

Information obtained from biodegradability tests, e.g. half-life (t(50)) or kinetics parameters, is relevant in environmental risk assessment of new chemicals. In these tests, the removal of the tested compound is measured over a prefixed period of time (e.g. 28 days in ready biodegradability tests) to derive a substrate depletion curve. The implementation can be time-consuming, costly and difficult, especially when the complexity of the environmental compartment increases. In this work, the possibility of obtaining a full biodegradation depletion curve from a single biodegradation-time experimental data point (‘single-data’ strategy) was evaluated. Monod kinetics are assumed to avoid the limitations related to first-order kinetics (only valid for very low substrate concentrations). Experimental and simulated data were used to illustrate the potential of the proposed strategy. The effects on the estimates of several variables (e.g. Monod kinetics parameters, compound concentration or variability in biodegradation data) and the errors introduced to some of the variables were also evaluated. The results suggest that the proposed strategy can be used as a rapid (based on data measured at day 7) and low-cost screening approach to anticipate the result of a biodegradability test for new chemicals. The applicability and practical limitations of the ‘single-data’ strategy have been illustrated using experimental data for several compounds ranging from readily biodegradable (e.g. benzoic acid, acetylsalicylic acid, p-toluic acid) to potentially persistent compounds (e.g. bupivacaine, p-phenitidine, phtadinitrile).

Endeavor to discover biorational natural products-based insecticides, two series (30) of novel (9S)-acyloxy derivatives of quinidine and dihydroquinidine were prepared and assessed for their insecticidal activity against Mythimna separata in vivo by the leaf-dipping method at 1 mg/mL. Among all the compounds, especially four derivatives exhibited the best insecticidal activity with final mortality rates of 71.4 %, 75.0 %, 71.4 %, and 75.0 %, respectively. Relatively speaking, 9-hydroxy group is well tolerated, and the results showed that after modification of the hydroxy group with an acyloxy group, the insecticidal activity was significantly increased; the configuration at C8/9 position is important for insecticidal activity, and the (9S)-configuration is optimal; modification of the out-ring double bond is acceptable, and hydrogenation of the double bond enhances insecticidal activity. These preliminary results will pave the way for further modification of quinidine in the development of potential new insecticides.
