Acid catalyzed carboxymethylation of alcohols is an emerging organic transformation that has grabbed the attention of scientific community in recent years. In the present study, sulfonated mesoporous polymer (MP-SO3H) is presented as a highly active solid acid catalyst to convert a wide range of alcohols into alkyl methyl carbonates. The remarkable catalytic activity of MP-SO3H is comparable to that of reported homogeneous acid catalysts. A good correlation was established between the catalytic activity and textural properties of the material. An exceptional catalytic activity of MP-SO3H was observed for DMC mediated carboxymethylation of bio-derived alcohols which is unmatchable to conventional resins and zeolites. This superior activity of MP-SO3H is ascribed to its intrinsic mesoporosity, high acid strength and uniform coverage of surface area by active sites. The catalyst is recyclable, resistant towards leaching and can be used in successive runs without losing the original activity. To the best of our knowledge, MP-SO3H is the first solid acid catalyst to exemplify highest activity for the synthesis of different alkyl methyl carbonates using DMC. The protocol developed herein opens up new avenues to transform wide range of bio-alcohols into useful organic carbonates in the future.

Chlorine is the 20th most abundant element on the earth compared to bromine, iodine, and fluorine, a sulfonimide reagent, N-chloro-N-(phenylsulfonyl)benzenesulfonamide (NCBSI) was identified as a mild and selective oxidant. Without activation, the reagent was proved to oxidize primary and secondary alcohols as well as their symmetrical and mixed ethers to corresponding aldehydes and ketones. With recoverable PS-TEMPO catalyst, selective oxidation over chlorination of primary and secondary alcohols and their ethers with electron-donating substituents was achieved. The reagent precursor of NCBSI was recovered quantitatively and can be reused for synthesizing NCBSI. (C) 2021 Elsevier Ltd. All rights reserved.

The complex pathogenesis of Alzheimer’s disease (AD) has become a major obstacle in its therapy. One hopeful approach is to develop multifuntional ligands. Here, a total of 23 compounds based on nobiletin structure were designed and synthesized. The neuroprotective activities were evaluated for their antioxidant, anti-inflammatory and anti-A beta(42) (Amyloid beta-protein 42) neurotoxicity properties by MTT assays. The results demonstrated compound A12 was the most promising derivative against inflammatory (14.6 +/- 0.6 %) and cell damages induced by hydrogen peroxide (47.2 +/- 1.1 %), oxygen glucose deprivation (36.2 +/- 1.1 %) and A beta(42) (40.7 +/- 2.1 %). Molecular docking study revealed A12 formed a greater area of interactions with A beta(42) to prevent it from acquiring a beta sheet conformation for aggregation. Structure-activity relationships revealed the introduction of hydroxyl on ring B and aurone skeleton with a five-membered ring C could be benefit to increase their neuroprotective activities. In summary, A12 might represent a promising multifunctional neuroprotective agent against AD.

Owing to hindered diffusions, the application of porous catalytic materials has been limited to relatively simple organic transformations with small substrates. Herein we report a dimensional reduction strategy to construct a two-dimensional metal-organic framework (MOF), Zr6OTf-BTB, with 96% accessible Lewis acidic sites as probed by the bulky Lewis base pivalonitrile. With nearly free substrate accessibility, Zr6OTf-BTB outperformed two three-dimensional MOF counterparts of similar Lewis acidity (Zr6OTf-BPDC and Zr6OTf-BTC) in catalyzing sterically hindered multicomponent reactions (MCRs) for the construction of tetrahydroquinoline and aziridine carboxylate derivatives with high turnover numbers (TONs). Zr6OTf-BTB was also superior to the homogeneous benchmark Sc(OTf)(3) with nearly 14 times higher TON and 9 times longer catalyst lifetime. Furthermore, the topology-activity relationships in these Zr-based Lewis acidic MOFs were rationalized by comparing their Lewis acidity, numbers of Lewis acidic sites, and sterically accessible Lewis acidic sites. Zr6OTf-BTB was successfully used to construct several bioactive molecules via MCRs with excellent efficiency. This dimensional reduction strategy should allow the development of other MOF catalysts for synthetically useful and complicated organic transformations.

A Ru-II-NH3 complex, 2, was oxidized through a proton-coupled electron transfer (PCET) mechanism with a Ce-IV complex in water at pH 2.5 to generate a Ru-v=NH complex, 5. Complex 5 was characterized with various spectroscopies, and the spin state was determined by the Evans method to be S = 1/2. The reactivity of 5 in substrate C-H oxidation was scrutinized in acidic water, using water-soluble organic substrates such as sodium ethylbenzene-sulfonate (EBS), which gave the corresponding 1-phenylethanol derivative as the product. In the substrate oxidation, complex 5 was converted to the corresponding Ru-III-NH3 complex, 3. The formation of 1-phenylethanol derivative from EBS and that of 3 indicate that complex 5 as the oxidant does not perform nitrogen-atom transfer, in sharp contrast to other high-valent metal-imido complexes reported so far. Oxidation of cyclobutanol by 5 afforded only cyclobutanone as the product, indicating that the substrate oxidation by 5 proceeds through a hydride-transfer mechanism. In the kinetic analysis on the C-H oxidation, we observed kinetic isotope effects (KIEs) on the C-H oxidation with use of deuterated substrates and remarkably large solvent KIE (sKIE) in D2O. These positive KIEs indicate that the rate-determining step involves not only cleavage of the C-H bond of the substrate but also proton transfer from water molecules to 5. The unique hydride-transfer mechanism in the substrate oxidation by 5 is probably derived from the fact that the Ru-IV-NH2 complex (4) formed from 5 by 1e(-)/1H(+) reduction is unstable and quickly disproportionates into 3 and 5.

The design and application of environmentally friendly catalysts to reduce the quantity of toxic wastes is critical for improving the chemical synthesis process. Therefore, BaFe12O19/Al2O3, a magnetic mesoporous nanocomposites, were designed synthesized and characterized using different techniques such as energy dispersive X-ray (EDX) spectroscopy, X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), field emission scanning electron microscopy (FESEM), Brunauer-Emmett-Teller (BET) adsorption method, and vibrating sample magnetometry (VSM). The prepared BaFe12O19/Al2O3 display a high surface area (1773.22 m(2)/g) with an average pore diameter of 3.946 nm from nitrogen sorption analysis. In addition, the synthesized nanocomposites prove to be an active heterogeneous Lewis acid catalyst for the solvent free synthesis of alpha-aminophosphonates at ambient temperature, through three-component reaction of aldehydes/ketones, amines and triethyl phosphite. The use of this catalyst results in an effortless magnetic recoverability and recyclability, high yield and short reaction time under solvent-free conditions. Graphic

Cyanobacteria is blue-green microalgae that produces a variety of secondary metabolites such as antibiotic, cytotoxic and antimicrobial agents. Present investigation proposed to study an extraction of active agents from Cyanobacteria and its antibacterial activity. The Cyanobacteria were collected, and isolated colony was found to be Oscillatoria sp. and it was grown in BG 11 medium for mass cultivation. Then the centrifuged biomass was weighed and used for extraction of bioactive compounds. GCMS analysis from Oscillatoria sp. determines fatty acid, triazine derivatives, pyridine derivatives, acridine derivatives. The result revealed that Oscillatoria sp. can play crucial roles as antibacterial agents because the methanolic extract are inhibiting the growth of S. aureus for gram-positive whereas P. aeruginosa for gram-negative bacteria. The crude extract was effective against S. aureus with the highest concentration, 100 mg/ml where area of the zone was 14.10 +/- 0.8 mm. The crude extract actively inhibited P. aeruginosa at 75 and 100 mg/ml with highest area of inhibition were in the average of 13.23 +/- 0.1 and 15.43 +/- 0.2 mm. Finally, the antimicrobial activity was carried out by disc diffusion method with different concentrations of active compounds shows the MIC value in gram-positive bacteria was 30 mu g/ml whereas for gram-negative bacteria was 25 mu g/nnl. Cyanobacteria extract should be preferred and considered to be new natural drug or antibiotics in pharmaceutical and health care industry. This coastal region should be studied further by researchers to study more information and benefits in the future.

An iron-catalysed allylation of organomagnesium reagents (alkyl, aryl) with simple allyl acetates proceeds under mild conditions (Fe(OAc)(2) or Fe(acac)(2), Et2O, r.t.) to furnish various alkene and styrene derivatives. Mechanistic studies indicate the operation of a homotopic catalyst. The sequential combination of such iron-catalysed allylation with an iron-catalysed hydrogenation results in overall C(sp(3))-C(sp(3))-bond formation that constitutes an attractive alternative to challenging direct cross-coupling protocols with alkyl halides.
