A class of zwitterionic organocatalysts based on an amide anion/iminium cation charge pair has been developed. The zwitterions are easily prepared by reacting aziridines with aminopyridines. They are catalytically applicable to transesterifications and dehydrative esterifications. Mechanistic studies reveal that the amide anion and iminium cation work synergistically in activating the reaction partners, with the iminium cationic moiety interacting with the carbonyl substrates through nonclassical hydrogen bonding. The reaction can be applied to large-scale synthesis of biodiesel under mild conditions.

A photoinduced synthesis of S-aryl thiosulfonates through a three-component reaction of aryldiazonium tetrafluoroborates, sodium metabisulfite, and thiourea is achieved. The reaction scope generality with a range of aryldiazonium tetrafluoroborates is demonstrated. In this transformation, a radical coupling pathway is proposed with the insertion of sulfur dioxide in the presence of a photocatalyst under visible light irradiation. The organic sulfur motifs in S-aryl thiosulfonates originate from the convenient, cheap, and easily available thiourea and sodium metabisulfite.

The extensive development and use of new anthropogenic chemicals have inevitably led to their presence in aquatic environments. Surface waters affected by sewage effluents have been exposed to these new substances. In the present study, the occurrence of anthropogenic substances, including pharmaceuticals and industrial chemicals, was investigated in one of the major rivers in Korea, the Nakdong River. Furthermore, seasonal variations in their content were determined via annual monitoring. Through the suspect and non-target screening (SNTS) technique, 58 substances were newly identified in the river and integrated in the quantitative monitoring practice. The results revealed that niflumic acid and melamine exhibited the highest median concentrations, i.e., 320 ng/L and 11,000 ng/L, respectively. The results associated with seasonal change revealed that the concentration of a considerable number of substances increased in winter when the flow rate was low. Conversely, some substances exhibited high concentrations in summer (e.g., polyethylene glycol) and spring (e.g., niflumic acid). This was attributed to the seasonal changes in the consumption, prescriptions, or the application of alternative substances. These changes were also reflected by the risk quotient (RQ) values calculated from the concentration and toxicity values. Pharmaceuticals such as telmisartan and carbamazepine and industrial chemicals such as organophosphorus flame retardants (OPFRs) and melamine accounted for approximately 90% of the total RQ. Major substances prioritized using the production of the RQ value and the detection frequency included OPFRs and telmisartan. It is recommended that these results be reflected in future water quality monitoring plans. (C) 2020 Elsevier Ltd. All rights reserved.

The Name is Anthrone. Through research, I have a further understanding and discovery of 90-44-8.

Ball milling of calcium carbide (CaC2) enables the reaction of its ethynyl moiety with organic electrophiles. This was realized simply by co-milling CaC(2)with organic substrates in a sealed jar without the need for an additive or a catalyst. Various ketones including those bearing alpha-hydrogens were ethynylated in good yields at short reaction times. Aryl halides are also amenable substrates for this protocol as they furnish aryl ethynes through a benzyne intermediate. This method offers a practical and cheap alternative to the established procedures for introducing ethynyl functionalities.

A new series of 1,2,4-triazole was designed, synthesized, and characterized as remarkable antimicrobial and antioxidant agents. These heterocycles have been prepared from the cyclization reactions of Schiff bases 3(a-k) with phenylhydrazine by refluxing under the alkaline medium. The Schiff bases in turn were realized in good yields from the condensation reactions of N-phenylurea with different aromatic aldehydes. The structures of the intermediates 3(a-k) and final heterocycles 4(a-k) have been fully characterized through their spectral parameters.

Objectives: Brain metastases are common among patients with non-squamous non-small-cell lung cancer (NSCLC) and result in a poor prognosis. Consequently, such patients are often excluded from clinical trials. In Italy an expanded access program (EAP) was used to evaluate nivolumab efficacy and safety in this sub population outside a clinical trial. Materials and methods: In this EAP, nivolumab was available for patients with non-squamous NSCLC in progression after at least one systemic treatment for stage IIIB/IV disease. Nivolumab 3 mg/kg was administered intravenously every 2 weeks. Patients with brain metastases could be included if they were asymptomatic, neurologically stable and either off corticosteroids or on a stable or decreasing dose of <= 10 mg/day prednisone. Results: 409 out of 1588 patients included had asymptomatic or controlled brain metastases. A median of 7 doses (range 1-45) were delivered. Median follow-up was 6.1 months (range 0.1-21.9). The disease control rate was 39%: 4 patients had a complete response, 64 a partial response and 96 showed stable disease. At baseline, 118 patients were on corticosteroids and 74 were undergoing concomitant radiotherapy. The median overall survival in this subpopulation was 8.6 months (95% CI: 6.4-10.8). 337 discontinued treatment for various reasons, 23 (7%) of whom due to adverse events, in line with that observed in the overall population and in previous studies. Conclusions: Our results confirm that nivolumab is active in non-squamous NSCLC patients with brain metastases, despite their poor prognosis. Its safety profile is also concordant with results in the EAP overall population and in patients with other malignancies. HPLC of Formula: C7H8N2O.

A novel method was used to prepare a magnetic phenylene-based periodic mesoporous organosilica nanocomposite with yolk-shell structure (Fe3O4@YSPMO). The Fe3O4@YSPMO nanomaterial was prepared by using easily accessible pluronic-P123 and cetyltrimethylammonium bromide (CTAB) surfactants under basic conditions. This material was employed for effective immobilization of potassium perruthenate to prepare an Fe3O4@YSPMO@Ru nanocatalyst for the aerobic oxidation of alcohols. The physiochemical properties of the designed Fe3O4@YSPMO@Ru nanocomposite were studied using PXRD, FT-IR, TGA, SEM, TEM, ICP, VSM and XPS analyses. Fe3O4@YSPMO@Ru was effectively employed as a highly recoverable nanocatalyst in the selective aerobic oxidation of alcohols.

A combination of DIBAL-H and Cp2ZrCl2 is shown to promote the regioselective cleavage of primary acetates on a broad scope of substrates, ranging from carbohydrates to terpene derivatives, with a high tolerance toward protecting groups and numerous functionalities found in natural products and bioactive compounds. Apart from providing highly valuable building blocks in only two steps from biosourced raw materials, this selective de-O-acetylation should also be strongly helpful to solve selectivity issues in organic synthesis.

The Name is Anthrone. Through research, I have a further understanding and discovery of 90-44-8.

Sulfate radical (SO4 center dot(-)) and hydroxyl radical (center dot OH) generated from persulfate or peroxymonosulfate in AOPs have been widely used in contaminant degradation. Anthracene (ANT) can be decomposed by SO4 center dot(-) and center dot OH. The processes of ANT decomposition were investigated using theoretical calculations in this paper. The initiation reactions of ANT, anthrone, anthraquinone (ATQ) and 1-hydroxylanthraquinone (1-hATQ) by two radicals are studied. The highest free energy barriers of initiation reactions are 22.30 kcal mol(-1) in ATQ + SO4 center dot(-) reaction and 6.84 kcal mol(-1) in ATQ + center dot OH reaction. Comparing the rate constants of initiation reaction through the two radicals at 273-373 K, it can be concluded that SO4 center dot(-) and center dot OH both play important roles on the initiation of ANT and anthrone at lower pH. For ATQ and 1-hATQ, center dot OH is more important than SO4 center dot(-) in the initiation process, which indicates that the indirect influence of SO4 center dot(-) are more significant in the degradation processes of ATQ and 1-hATQ. This study provides theoretical confirmations for the mechanisms of reactions of ANT with SO4 center dot(-) and center dot OH, and evaluates the importance of SO4 center dot(-) and center dot OH according to the reaction rates. The work can give more insight into the degradation of PAHs by radicals.
