Chiral ionic liquids (CILs) have shown a wide range of applications in variety of domains in chemistry. Because of this, synthesis and applications of CILs have always been areas of interest for research in the last 20 years. Present work describes, the synthesis of six carbohydrate based chiral ionic liquids (CCILs) by following simple procedures and their applications. Structures of the cats were confirmed through various analytical techniques like NMR spectroscopy (H-1, C-13, B-11, P-31,F-19), El-MS, and polarimetry. Designed CCILs were tested as chiral recognising agents using sodium salt of Mosher’s acid as model substrate through (FNMR)-F-19-N- spectroscopy. Further, Cats were used as organocatalyst in the enantioselective reduction of aromatic prochiral ketones to achieve corresponding chiral secondary alcohols. (C) 2019 Elsevier B.V.

SDS of cas: 100-19-6. I found the field of Psychology; Psychiatry very interesting. Saw the article Trajectories of depression symptom change during and following treatment in adolescents with unipolar major depression published in 2020.0, Reprint Addresses Davies, SE; Goodyer, IM (corresponding author), Univ Cambridge, Sch Clin Med, Dept Psychiat, 18b Trumpington Rd, Cambridge CB2 8AH, England..

Objective To classify a cohort of depressed adolescents recruited to the UK IMPACT trial, according to trajectories of symptom change. We examined for predictors and compared the data-driven categories of patients with a priori operational definitions of treatment response. Method Secondary data analysis using growth mixture modelling (GMM). Missing data were imputed. Trajectories of self-reported depressive symptoms were plotted using scores taken at six nominal time points over 86 weeks from randomisation in all 465 patients. Results A piecewise GMM categorised patients into two classes with initially similar and subsequently distinct trajectories. Both groups had a significant decline in depressive symptoms over the first 18 weeks. Eighty-four per cent (84.1%, n = 391) of patients were classed as ‘continued-improvers’ with symptoms reducing over the duration of the study. A further class of 15.9% (n = 74) of patients were termed ‘halted-improvers’ with higher baseline depression scores, faster early recovery but no further improvement after 18 weeks. Presence of baseline comorbidity somewhat increased membership to the halted-improvers class (OR = 1.40, CI: 1.00-1.96). By end of study, compared with classes, a clinical remission cut-off score (<= 27) and a symptom reduction score (>= 50%) indexing treatment response misclassified 15% and 31% of cases, respectively. Conclusions A fast reduction in depressive symptoms in the first few weeks of treatment may not indicate a good prognosis. Halted improvement is only seen after 18 weeks of treatment. Longitudinal modelling may improve the precision of revealing differential responses to treatment. Improvement in depressive symptoms may be somewhat better in the year after treatment than previously considered.

An efficient, simple and highly versatile method for the preparation of quinoline derivatives was developed via the Friedlander annulation reaction of 2-aminoarylketones with carbonyl compounds using copper-incorporated sulfated zirconium oxide (ZrO2/SO42-/Cu) as a heterogeneous recyclable nanocatalyst. The catalyst was characterized by FTIR, TG-DTG, XRD, EDX, FE-SEM and TEM analyses. Surface acidity of the catalyst was measured by pyridine adsorption followed by FTIR spectroscopy. The catalyst contains various Lewis- and Bronsted acid sites, which along with the incorporated copper, provides high to excellent yields for all compounds in water as a green solvent at room temperature for short reaction times. The catalyst could be efficiently reused for several runs without any appreciable loss of activity. In addition, the scalability of the process was investigated in this work. Finally, a plausible reaction mechanism was suggested for this transformation.

The starting precursors 2-carbohydrazides, bearing thienopyridine moiety, were prepared using 2-thioxopyridine-3-carbonitriles as key synthons. Next, 2-carbohydrazides were reacted with a variety of 4-substituted benzylidinemalononitriles or 4-substituted benzaldehydes to afford a new series of the target hydrazones incorporating thienopyridine moiety. The elemental analyses and spectral data were used to demonstrate the structures of new hydrazones series. The in vitro antibacterial activities of the target hydrazones were evaluated against different strains of Gram-positive and Gram-negative bacteria. In comparison with chloramphenicol as a reference drug, hydrazones 13b, 13c and 13d, linked to p-C1, p-Br and p-Me moiety, respectively, exhibited the strongest activities against all tested bacteria with MIC values in the range of 6.2-12.5 mu g/mL. In addition, several new hydrazones were tested as in vitro cytotoxic agents against each of human breast carcinoma MCF-7 cell line, colon cancer Caco2 cell line and liver hepatocellular carcinoma HEPG2 cell line. The hydrazones 13b, 13c and 13d demonstrated the best cytotoxicity against the tested eukaryotic cells. Furthermore, both experimental and docking studies could predict the promising inhibitory activities of hydrazones 13c and 13d against COX-2 enzyme with IC 50 of 0.110 and 0.104 mu M, respectively, when compared with Celecoxib (IC50 of 0.115 mu M).

3,6-Di(pyridin-2-yl)-1,2,4,5-s-tetrazine capped-silver nanoparticles (TzAgNPs) exhibit an excellent catalytic activity and chemoselectivity for the reduction of various substituted nitroarenes to the corresponding aromatic amines in aqueous medium with sodium borohydride and hydrazine hydrate as a hydrogen donor at room temperature. The reaction kinetics of the reduction of 4-nitrophenol to 4-aminophenol has also been studied to determine the apparent rate constant. The catalyst TzAgNPs efficiently reduces the nitro group under very mild conditions, thus affording excellent yields within very short reaction time (<20 min), and shows high selectivity even in the presence of other sensitive functional groups.

Protection techniques of functional groups within the structure of organic compounds are important synthetic methods against unwanted attacks from various reagents during synthetic sequences. Acetal and thioacetal groups are well known as protective functional groups in organic reactions. In this study, acetalization of carbonyl compounds with diols and dithiols and methoxymethylation of alcohols with formaldehyde dimethyl acetal (FDMA) have been carried out using sulfamic acid-functionalized magnetic Fe3O4 nanoparticles (SA-MNPs) as a heterogeneous solid acid catalyst. Products were characterized by FT-IR and NMR spectroscopies. The structural and electronic properties of some products were computed by quantum mechanical (QM) methods. Depending on the stereochemistry and electronic properties that were obtained by computational results, we have suggested that hyperconjugation plays a key role in the structural properties of 2-phenyl-1,3-dioxolane derivatives, and also the electron transfer between pi-electrons of the aromatic ring with the 3d orbital of S-atoms influences the 2-phenyl-1,3-dithiane derivatives’ structure.

Hydroboration of carbonyl compounds is an important transformation in organic chemistry, and a growing interest in catalysis has focused on abundant and nontoxic base metals. Herein we describe an efficient salen manganese catalyst for the hydroboration of a broad range of carbonyl compounds with pinacolborane. The catalytic reactions proceeded rapidly (>99% conversion in <5 min) at room temperature with very low catalyst loadings. High turnover frequency (up to 5700 h(-1)) was observed under these conditions. Several synthetically important functional groups were tolerated, and chemoselective hydroboration of aldehydes over ketones was achieved. The H/D kinetic isotopic effect of borane was determined to be 2.3. The Hammett correlation plot of a series of para-substituted acetophenone substrates, p-X-C6H6COCH3 (X = H, Me, OMe, NO2, Cl, Br, and CF3) yielded a positive slope of rho = +0.99. The crossover products were detected in the competition reaction of catecholborane and deuterated pinacolborane with acetophenone. The findings indicated a potential borane-mediated pathway that could account for the observation of the crossover products. Formula: C8H7NO3.

A family of ferrocene-based chiral PNP ligands is reported. These tridentate ligands were successfully applied in Mn- catalyzed asymmetric hydrogenation of ketones, giving high enantioselectivities (92%similar to 99% ee for aryl alkyl ketones) as well as high efficiencies (TON up to 2000). In additiondialkyl ketones could also be hydrogenated smoothly. Manganese intermediates that might be involved in the catalytic cycle were analyzed. DFT calculation was carried out to help understand the chiral induction model. The Mn/PNP catalyst could discriminate two groups with different steric properties by deformation of the phosphine moiety in the flexible 5-membered ring.
