The synthesis of alpha,beta-unsaturated ketones from aerobic oxidation of allylic alcohols and biobased olefins serves as an important topic in green and sustainable chemistry. In this work, we report the utilization of a sacrificial template ZIF-8 for preparation of mesoporous Co-0.05/N-C material with an ultralow cobalt loading of 0.05 wt %, in which the excellent catalytic performance in aerobic oxidation of alpha-pinene and cinnamyl alcohol was achieved with an 85% yield of verbenone and a yield of cinnamaldehyde, respectively. The results of control experiments and several characterization investigations further illustrate that the sacrificial template ZIF-8 plays a key role to disperse well metallic cobalt in the Co-0.05/N-C-800 catalyst and an appropriate cobalt content of 0.05 wt % is beneficial for benign and efficient aerobic oxidation of various allylic alcohols and biobased olefins. In addition, the Co0.05/N-C-800 catalyst also exhibited good stability and reusability for recovering and reusing at least six times without obvious decrease in catalytic activity. The presented efficient nanocatalyst thus triggers facile synthesis of a series of alpha,beta-unsaturated aldehydes/ketones in high yields.

New sulfonamide-hydrazone derivatives (3a-3n) were synthesized to evaluate their inhibitory effects on purified human carbonic anhydrase (hCA) I and II. The inhibition profiles of the synthesized compounds on hCA I-II isoenzyme were investigated by comparing their IC50 and K-i values. Acetazolamide (5-acetamido-1,3,4-thia-diazole-2-sulfonamide, AZA) has also been used as a standard inhibitor. The compound 3e demonstrated the best hCA I inhibitory effect with a K-i value of 0.1676 +/- 0.017 mu M. Besides, the compound 3m showed the best hCA II inhibitory effect with a K-i value of 0.2880 +/- 0.080 mu M. Cytotoxicity of the compounds 3e and 3m toward NIH/3T3 mouse embryonic fibroblast cell line was observed and the compounds were found to be non-cytotoxic. Molecular docking studies were performed to investigate the interaction types between active compounds and hCA enzymes. Pharmacokinetic profiles of compounds were assessed by theoretical ADME predictions. As a result of this study a novel and potent class of CA inhibitors were identified with a good activity potential.

Novel task dicationic ionic liquids (Ts-DilLs) 6-29 were designed and synthesized, under both conventional and microwave conditions; through molecular hybridization of the appropriate bispyridines having a hydrazone linkage as spacer with some alkyl functionalized esters forming the counter cations. Beside the synthesized halogenated DilLs 6-11, fluorinated metal anions were introduced via metathesis reaction in order to create new dipyridinium ionic liquid-hydrazone hybrids 12-29. All newly synthesized DilLs were fully characterized using different spectroscopic tools such as H-1, C-13, F-19, P-31, B-11 NMR and Mass experiment. The DNA binding, anticancer and docking studies of the synthesized ionic liquids were also carried out. The DNA binding constants ranged from 4.5 x 10(4) to 7.2 x 10(4) M-1, indicating good DNA binding tendencies. The most active ionic liquids were 28 and 29 with 99.99 and 99.86% anticancer activities, respectively. The docking studies indicated DNA binding in the outer grooves of DNA. The reported ionic liquids may be used as future anticancer drugs. (C) 2020 Elsevier B.V. All rights reserved.

Here we present a comprehensive study on the [3+2]-cycloaddition of thiocarbonyl ylides with a wide variety of alkenes and alkynes. The obtained dihydro- and tetrahydrothiophene products serve as exceptionally versatile intermediates providing access to thiophenes, dienes, dendralenes, and vic-quarternary carbon centers. The use of high-pressure conditions enables thermally unstable, sterically encumbered or moderately reactive substrates to undergo the cycloaddition under mild conditions, thereby increasing the yield by up to 58%. In addition, we showcase its utility by the formal syntheses of the pharmaceuticals NGB 4420 and tenilapine.

Thiourea-organocatalyzed Michael additions of diethyl malonate to various heteroaromatic nitroolefins (13 examples) have been studied under high-pressure (up to 800 MPa) and ambient pressure conditions. High pressure was conducive to enhanced product yields by a factor of 2-12 at a given reaction time, high reaction rates (reaction times were decreased from 72-24 h down to 4-24 h) and high enantioselectivity. Elucidating the effects of solvents for maximizing reaction rates and yields has been carried out using the Perturbed-Chain Polar Statistical Associating Fluid Theory (PCP-SAFT), allowing for the first time a prediction of the kinetic profiles under high-hydrostatic-pressure conditions.

The anti-selective direct asymmetric Mannich reaction of (hetero) aromatic aldehydes, 4-anisidine and O-protected hydroxyacetones for the synthesis of stereodefined anti-beta-amino-alpha-hydroxycarbonyl compounds was developed. Protease type XIV from Streptomyces griseus (SGP) was used as a biocatalyst in 1,4-dioxane/phosphate buffer under mild reaction conditions. The excellent diastereoselectivities of up to >99:1 (anti/syn) and good enantioselectivities of up to 90% ee were achieved. This method provides a more sustainable complement to chemically catalyzed anti-selective direct asymmetric Mannich reactions. (C) 2019 Elsevier Ltd. All rights reserved.

The exceptionally mild conditions of a titanium(III)-catalyzed cyclization reaction paired with a convenient acid/base extraction have enabled the straightforward synthesis, isolation, and direct N-functionalization of amino heterocycles such as 3-aminoindoles and -pyrroles. The unprotected heterocycles are ideal building blocks for the installation of aminated indoles and pyrroles into target molecules, but their sensitivity has previously impeded their synthesis by modern catalytic methods. This full paper presents the development and extended scope of the new cyclization methodology. The transformation of the products into fused bis-indoles is also demonstrated along with the discovery of an unusual palladium-catalyzed reductive biphenyl coupling reaction. The titanium(III)-catalyzed cyclization has also been applied to the synthesis of substituted 3-iminoindolines, which are of potential interest for applications in natural product synthesis and exhibit tunable blue-to-green fluorescence properties.

A wide range of alkyl, aryl and hetero-aryl aldehydes reacted with 2-pyridylacetonitrile and isocyanides, leading to indolizine derivatives with high selectivity, high atom economy, and good to excellent yields. This straight-forward and highly efficient method allows the synthesis of bis-indolizine-1-carbonitrile derivatives.
