The organocatalytic enantio- and diastereoselective cycloetherification of 1,3-cyclohexanedione-bearing enones involving the in situ generation of chiral cyanohydrins was developed. This transformation offers the first catalytic asymmetric approach to oxadecalin derivatives containing contiguous tetrasubstituted chiral carbons at the bridge heads of the fused ring systems. Depending on substituents, both cis- and trans-decalin-type scaffolds were synthesized with good to excellent stereoselectivities, and a range of functional groups accumulated on the chiral quaternary carbon moieties of the trans-oxadecalin derivatives.

Because it is undisputable that lignin depolymerization is a must to make the biorefinery concept economically feasible, several efforts are put toward it; however, a lot of catalyst designing is required to achieve efficient depolymerization activities. In this work, we show a systematic approach in the synthesis and characterization of ionic liquids (ILs) with varying combinations of cations (imidazole, benzimidazole, phosphonium, and ammonium) and anions (HSO4, PTS (p-toluenesulfonate), Cl, H2PO4, SnCl3, FeCl4, and CuCl3) for the depolymerization of lignin into low-molecular weight aromatic fractions (<220 g/mol) under mild reaction conditions (120 degrees C, 1 h, ambient pressure). In a methodical approach, effects of various reaction parameters such as temperature (70-170 degrees C), time (15-360 min), pressure (N-2, 0.5-3 MPa), solvents and substrate, and so forth were studied to achieve best activity. Among all the catalysts, IL with the imidazolium cation and HSO4 as the anion showed best activity (78% yield). Subsequent to depolymerization, three aromatic monomers (5 wt % pure vanillin) were isolated using flash column chromatography. These aromatic monomers were characterized using gas chromatography (GC), GC-mass spectrometry, and NMR techniques for their purity. Hammett acidity functions (H-0) of ILs were measured using UV-vis photo-spectroscopy, and values are correlated with lignin depolymerization results. Lignin and tetrahydrofuran-soluble products were thoroughly characterized using assorted physicochemical techniques such as NMR (H-1 and C-13), gel permittivity chromatography, thermogravimetric analysis, and so forth. The catalyst was recycled up to six runs and showed similar results in consecutive reactions.

The direct C-H arylation and acylation of azoles with carboxylic acids were achieved through Pd/Cu cooperative catalysis. Various biaryls and biaryl ketones were selectively produced in good to high yields from the same substrates. The key factor of high chemoselectivity was the choice of a suitable phosphine ligand: biaryls were generated selectively with dppp as the ligand, while biaryl ketones were obtained with high selectivity using dpph or Ph2PCy as the ligand.

Present work demonstrates synthesis and antibacterial property of new pyrazole derivatives. A series of new Curcumin based dihydropyrazoles has been synthesized with an objective to evaluate their antibacterial property. Dihydropyrazoles analogues were synthesized using Curcumin based chalcones and differently substituted phenylhydrazine derivatives. We used the previously designed Curcumin based chalconesto react with phenylhydrazine derivatives in ethanol in a catalyst free medium to afford new dihydropyrazole derivatives. Effect of substituent on reactivity was also studied. All the synthesized pyrazole analogues were characterized using proton and carbon NMR, Mass spectroscopy and IR techniques. Effect of substituent on reactivity was explained on the basis of electronic effect generated due to groups on phenyl ring. Presence of dd (double doublet) in proton NMR spectrum of Dihydropyrazoles was also explained due to presence of optically active carbon of pyrazole ring. The synthesized library was screened for their inhibitory activity against 4 different bacterial strains 1. E. Coli (ATCC 9637), 2. Pseudomonas aeruginosa (ATCC BAA-427), 3. Staphylococcus aureus (ATCC 25923) and 4. Klebsiella pneumonia (ATCC 27736). Out of all the compounds evaluated, the compounds that exhibited IC50 value greater than 50 mu M, were considered to be inactive. We established an important SAR based on the structure dependent inhibitory potential of screened dihydropyrazoles. Two compounds 4e and 4t having nitro and benzyl substitution respectively were showing the best inhibitory potential against Gram Positive bacterial strain Staphylococcus aureus with MIC value of 1.56 mu g/ml. Compounds having Chloro and Methoxy substitution were found to be less effective against screened bacterial strains. Compounds 4a and 4b were selective towards Staphylococcus aureus species with the MIC value of 1.56 mu g/ml for each. These pyrazole analogues were not showing inhibitory potential against other screened bacterial strains.

Unprecedented triazinyl-isoxazoles were afforded via an effective cycloaddition reaction between nitrile oxides and the scarcely described 2-ethynyl-4,6-dimethoxy-1,3,5-triazine as dipolarophile. The biological evaluation of the newly synthesized compounds showed that the inhibition of human farnesyltransferase by zinc complexation could be improved with triazine-isoxazole moieties. The replacement of the isoxazole unit by a pyrrolidin-2-one was detrimental to the inhibitory activity while the pyrrolidin-2-thione derivatives conserved the biological potential. The potential of selected compounds to disrupt protein farnesylation in Chinese hamster ovary (CHO) cells transfected with pEGFP-CAAX was also evaluated.

The absorption of electromagnetic waves by materials is usually realized by multiple mechanisms, such as interface polarization, defect polarization, multiple reflections and scattering, conductive loss and magnetic loss. Therefore, attributing microwave absorption (MA) to specific mechanisms without separating them through effective means is not rigorous. Herein, three different structures: ZnO-C core-shell nanowires, ZnO-C wire-in-tubes and carbon nanotubes, were prepared through the molecular layer deposition of polyimide on ZnO nanowires and subsequent calcination at specific temperatures. Results show that the hollow structure is beneficial to MA performance. The reflection loss (RL) values of wire-in-tube and nanotube structures are much higher than the RL values of the core-shell structure. The RL peak of nanotube structure can reach -64.42 dB. Then again, multicomponent modulation is conducive to impedance matching resulting in board effective absorption bandwidth (EAB). The EAB of the wire-in-tube structure with two components is wider than that of the nanotube structure with one component, reaching as wide as 5.76 GHz. The results substantiate the effect of hollow structure and composition on the MA performance, providing a strong basis for the design and optimization of MA materials. (C) 2020 Elsevier Ltd.

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.
