The B3NO2 six-membered heterocycle (1,3-dioxa-5-aza-2,4,6-triborinane = DATB), comprising three different non-carbon period 2 elements, has been recently demonstrated to be a powerful catalyst for dehydrative condensation of carboxylic acids and amines. The tedious synthesis of DATB, however, has significantly diminished its utility as a catalyst, and thus the inherent chemical properties of the ring system have remained virtually unexplored. Here, a general and facile synthetic strategy that harnesses a pyrimidine-containing scaffold for the reliable installation of boron atoms is disclosed, giving rise to a series of Pym-DATBs from inexpensive materials in a modular fashion. The identification of a soluble Pym-DATB derivative allowed for the investigation of the dynamic nature of the B3NO2 ring system, revealing differential ring-closing and -opening behaviors depending on the medium. Readily accessible Pym-DATBs proved their utility as efficient catalysts for dehydrative amidation with broad substrate scope and functional-group tolerance, offering a general and practical catalytic alternative to reagent-driven amidation.

Formula: C7H6O2. I found the field of Biochemistry & Molecular Biology; Chemistry very interesting. Saw the article Inhibition of nitric oxide and prostaglandin E-2 production by pyrrolylated-chalcones: Synthesis, biological activity, crystal structure analysis, and molecular docking studies published in 2020.0, Reprint Addresses Faudzi, SMM (corresponding author), Univ Putra Malaysia, Fac Sci, Dept Chem, Serdang 43400, Selangor, Malaysia.. The CAS is 100-83-4. Through research, I have a further understanding and discovery of 3-Hydroxybenzaldehyde.

In search of potent anti-inflammatory agents, twenty-four chalcone derivatives including seven new compounds (13 – 17, 21 and 23) containing pyrrole moiety were designed, synthesized, and assessed for their nitric oxide (NO) and prostaglandin E-2 (PGE(2)) suppression ability on IFN-gamma/LPS-induced RAW 264.7 macrophage cells. Results showed that none of the synthesized compounds were PAINS-associated molecules, with 3-(2,5-dimethoxyphenyl)-1-(1H-pyrrol-2-yl) prop-2-en-1-one (compound 16) exhibiting remarkable inhibition activity towards PGE(2) and NO production with IC50 values of 0.5 +/- 1.5 mu M and 12.1 +/- 1.5 mu M, respectively. Physicochemical and ADMET studies showed that majority of the compounds obey to Lipinski’s rule of five (RO5) having high blood brain barrier (BBB) penetration, human intestinal absorption (HIA), P- glycoprotein (PgP) inhibition and plasma binding protein (PPB) inhibition. The obtained atomic coordinates for the single-crystal XRD of 16 were then applied in a molecular docking simulation, and compound 16 was found to participate in a number of important binding interactions in the binding sites of ERK and mPGES-1. Based on these results, we have observed the potential of compound 16 as a new hit anti-inflammatory agent, and these findings could serve as a basis for further studies on its mechanism of action.

Selective production of aromatic aldehydes is an important challenge in the synthesis of fine chemicals. This study presents a viable strategy for the production of benzaldehyde using a magnetic recoverable photocatalyst. Graphitic carbon nitride was submitted to a thermal post-treatment, for partial exfoliation (g-CN-T) and combined with magnetic nanoparticles of Fe3O4. The composite containing 18 wt.% of Fe3O4 shows a remarkable magnetic response. The efficiency of this composite was evaluated in the selective photocatalytic conversion of benzyl alcohol into benzaldehyde. A good compromise was observed in terms of selectivity for benzaldehyde formation and ability of recovery at the end of the photocatalytic reaction by the application of a magnetic field. Reutilization experiments using this hybrid material revealed a slight decrease of efficiency after the first run only. Moreover, hydrogen was generated during the photocatalytic production of benzaldehyde. Thus, the combination of gCN-T and magnetic nanoparticles provided an impetus to design a photocatalyst with easy and inexpensive features for selective synthesis of organic compounds.

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.

Chitosan decorated copper nanoparticles (CS/CuNPs) catalysts were synthesized via reduction methods utilizing green protocol. The CS/CuNPs hybrid catalysts were tested for the synthesis of quinoline derivatives utilizing one-pot multicomponent reaction (MCR) under ultrasonic irradiation. The optimized CS/CuNPs catalyst that provided good conversion reaction yield and high turnover frequency (TOF) was characterized using Fourier transform infrared (FTIR), thermogravimetric analyses (TGA), X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscope (TEM) and X-ray photoelectron spectroscopy (XPS) techniques. Generalization of the scope of the proposed catalytic process was studied using different aldehydes. Excellent products yield and high TOF in even shorter reaction time (similar to 5 min) was attained. Recyclability performance of the catalyst over five times re-use without detectable loss in product yield was recorded. The current method is green process utilizing environmentally benign catalyst and considered to be promising sustainable protocol for the synthesis of fine chemicals.

E-cigarettes have become very popular, a trend that has been stimulated by the wide variety of available e-liquid flavours. Considering the large number of e-liquid flavours (>7000), there is an urgent need to establish a screening strategy to prioritize the flavouring substances of highest concern for human health. In the present study, a prioritization strategy combining analytical screening, in silico tools and literature data was developed to identify potentially genotoxic e-liquid flavourings. Based on the analysis of 129 e-liquids collected on the Belgian market, 60 flavourings with positive in silico predictions for genotoxicity were identified. By using literature data, genotoxicity was excluded for 33 of them whereas for 5, i.e. estragole, safrole, 2-furylmethylketon, 2,5-dimethyl-4-hydroxyl-3(2H)-furanone and transhexanal, there was a clear concern for in vivo genotoxicity. A selection of 4 out of the remaining 22 flavourings was tested in two in vitro genotoxicity assays. Three out of the four tested flavourings induced gene mutations and chromosome damage in vitro, whereas equivocal results were obtained for the fourth compound. Thus, although there is a legislative framework which excludes the use of CMR compounds in e-liquids, flavourings of genotoxic concern are present and might pose a health risk for e-cigarette users.

Bridged biaryl atropisomers are important units in bioactive molecules. A synthesis of lactone-bridged biaryl atropisomers was realized by a Cu-catalyzed asymmetric ring-opening/acyoxylation of cyclic diaryliodoniums, followed by a palladium-catalyzed diastereoselective cyclization. It was found that a catalytic amount of Cu(OTf)(2) served as an additive to promote the palladium-catalyzed Heck cyclization.

The present investigation aims to synthesize and explore the influence of pyridine and pyran derivatives on the API X-65 steel corrosion in a 6 M H2SO4 solution. The compound was examined at different concentrations to optimized the best concentration for the corrosion inhibition effect, weight loss measurements, potentiodynamic polarization measurement (PDP), electrochemical impedance spectroscopy (EIS), scanning electron microscopy (SEM) and theoretical methods were used to evaluating the inhibition efficiency. The obtained adsorption data achieved the model of Langmuir isotherm. The pyridine derivatives showed higher inhibition than pyran derivatives. The PDP tests proposed that pyridine and pyran derivatives are mixed-type inhibitors. The EIS parameters demonstrate that the double-layer capacitance (C-dl) decreases with the increase of inhibitor concentration, which implies a reduces dielectric constant. It was observed from experimental data that the inhibition efficiency reached 92.7%, 89.1, 94.7, and 85.2% for concentration 2.66 x 10(-3)M of I, II, III and IV, respectively indicating the inhibition order is III > I > II > IV. The parameters derived from the theoretical quantum chemical calculations were found adequately correlated with the obtained experimental results.

One of the fundamental and highly valuable transformations in organic chemistry is the nucleophilic substitution of alcohols. Traditionally, these reactions require strategies that employ stoichiometric hazardous reagents and are associated with difficulty in purification of the by-products. To overcome these challenges, here, we report a simple route toward the diverse conversion of alcohols via an S(N)2 pathway, in which blue light-promoted iodination is used to form alkyl iodide intermediates from simple unreactive alcohols. The scope of the process tolerates a range of nucleophiles to construct C-N, C-O, C-S, and C-C bonds. Furthermore, we also demonstrate that this method can be used for the preparation and late-stage functionalization of pharmaceuticals, as highlighted by the syntheses of thiocarlide, butoxycaine, and pramoxine.
