An efficient and convenient method for the synthesis of various substituted pyrano[3,2-c]chromene-2,5-diones was developed via the I-2-promoted tandem cyclization of commercially available aryl methyl ketones and 4-hydroxycoumarins. Preliminary mechanism studies indicated that the reaction involved a consecutive iodination/Kornblum oxidation/annulation process. HI produced in the I-2-DMSO system acted as an important promoter, accelerating the annulation protocol. (C) 2019 Elsevier Ltd. All rights reserved.

Magnetic graphene quantum dots were prepared and incorporated in cyclodextrin decorated chitosan. The resulting hybrid was then palladated and characterized using TEM, BET, TGA, XRD, VSM, ICP and FTIR spectroscopy. Next, the catalytic activity of the prepared hybrid catalyst that benefits from the chemistry of both carbohydrates and magnetic graphene quantum dots was investigated for promoting hydrogenation reaction of nitroarenes in aqueous media under mild reaction condition. The study of the catalyst performance confirmed high catalytic activity and selectivity of the catalyst towards hydrogenation of the nitro group. Moreover, the catalyst could be magnetic-ally separated from the reaction mixture and recycled up to ten reaction runs with a slight loss of the catalytic activity and Pd leaching.These results showed that the hybrid of magnetic graphene quantum dots and carbohydrates is an efficient catalyst support that can be potentially applied for the immobilization of nanoparticles to furnish heterogeneous catalysts for promoting the chemical transformations.

Asymmetric catalysis with readily available, cheap, and non-toxic alkaline earth metal catalysts represents a sustainable alternative to conventional synthesis methodologies. In this context, we describe the development of a first Mg-II-catalyzed enantioselective hydroboration providing the products with excellent yields and enantioselectivities. NMR spectroscopy studies and DFT calculations provide insights into the reaction mechanism and the origin of the enantioselectivity which can be explained by a metal-ligand cooperative catalysis pathway involving a non-innocent ligand.

The appropriate pyridine-2(1H)-thiones were reacted with an equivalent amount of 5-(chloromethyl)-2-hydroxybenzaldehyde in ethanol in the presence of potassium hydroxide to give the corresponding 2-hydroxybenzaldehyde derivatives in excellent yields. The latter derivatives were taken as key synthons for the preparation of the target hybrids. Therefore, 2-hydroxybenzaldehydes were reacted with benzoylglycine in acetic anhydride in the presence of fused sodium acetate at 100 degrees C for 6 hours to afford a new series of nicotinonitrile-coumarin hybrids. The in vitro acetylcholinesterase inhibitory activities were estimated for the new coumarins. The results were expressed as the inhibition percentage of the tested hybrids at concentration of 25 nM, compared to donepezil as a reference (inhibition percentage of 70.5). Coumarin hybrids linked to 6-(4-nitrophenyl) or 6-(4-chlorophenyl)-4-phenylnicotinonitrile exhibited more effective inhibitory activities than donepezil with inhibition percentages of 94.1 and 72.3, respectively. The new coumarins were tested for their free radical-scavenging capabilities against DPPH. Furthermore, some new coumarins were tested for in vitro cytotoxic activity against each MCF-10A, MCF-7, Caco2, and HEPG2. The new hybrids showed cytotoxicity in micromolar range (IC(50)of 3.5-13.9 mu M) against all tested cell lines. These results clearly demonstrated that the hybrids being tested are not cytotoxic at the concentration required to inhibit acetylcholinesterase effectively.

A Lewis base supported terminal uranium phosphinidene, [eta(5)-1,3-(Me3C)(2)C5H3]2U(= P-2,4,6-(Bu3C6H2)-Bu-t)(OPMe3) (5), is isolated from the reaction of the uranium methyl chloride [eta(5)- 1,3-(Me3C)(2)C5H3](2)U(Cl) Me (4) with 2, 4, 6-(Me3C)(3)C6H2PHK in toluene in the presence of Me3PO. Moreover, the reactivity of uranium phospinidene 5 toward a series of small molecules was comprehensively explored. While no reactivity of 5 with internal alkynes is observed attributed to steric hindrance, it readily reacts in good yields with various small molecules including isothiocyanates, aldehydes, imines, diazenes, carbodiimides, nitriles, isonitriles, and organic azides, yielding uranium sulfidos, oxidos, metallaheterocycles, and imido complexes.

A pathway for the catalytic hydrosilylation of carbonyl substrates with M(C6F5)(3) (M = B, Al and Ga) was calculated by DFT (B3PW91-D3) and it was shown that in the case of the Al reagent, the carbonyl substrate binds irreversibly and inhibits catalysis by generating a stable carbonyl adduct. In contrast, the reduced electrophilicity of B(C6F5)(3) disfavors the binding of the carbonyl substrate and increases the concentration of an activated silane adduct which is the species responsible for catalytic turnover. A similar mechanism was found for both cationic and neutral Re(III) species. Further, it was shown by tuning the electrophilicity of the rhenium catalysts, conditions can be found that would enable the catalytic hydrosilylation of ketone and nitrile substrates that were unreactive in previously reported systems. Thus the mechanisms proposed in this work, lay the foundation for the design of new catalytic systems.

A new concept for selectivity control in carbocation-driven reactions has been identified which allows for the chemo-, regio-, and stereoselective addition of nucleophiles to alkynes-assisted vinyl cation formation-enabled by a Li+-based supramolecular framework. Mechanistic analysis of a model complex (Li2NTf2+center dot 3H(2)O) confirms that solely the formation of a complex between the incoming nucleophile and the transition state of the alkyne protonation is responsible for the resulting selective Naddition to the vinyl cation. Into the bargain, a general, operationally simple synthetic procedure to previously inaccessible vinyl triflimides is provided.

The effect of the pore size of nanoporous gold on electrochemical reduction of functionalized carbonyl compounds was investigated. NPG with a pore size of similar to 30 nm significantly enhanced the reactivity with high chemo-selectivity at a low-potential. Typically, p-nitrobenzaldehyde reduction demonstrates a high turnover frequency (TOF) up to 232 000 h(-1).

Deprotonation of the Mn-I NHC-phosphine complex fac-[MnBr(CO)(3)(k(2)P,C-Ph2PCH2NHC)] (2) under a H-2 atmosphere readily gives the hydride fac-[MnH(CO)(3)(k(2)P,C-Ph2PCH2NHC)] (3) via the intermediacy of the highly reactive 18-e NHC-phosphinomethanide complex fac-[Mn-(CO)(3)(k(3)P,C,C-Ph2PCHNHC)] (6a). DFT calculations revealed that the preferred reaction mechanism involves the unsaturated 16-e mangana-substituted phosphonium ylide complex fac-[Mn(CO)(3)(k(2)P,C-Ph2P=CHNHC)] (6b) as key intermediate able to activate H-2 via a non-classical mode of metal-ligand cooperation implying a formal lambda(5)-P-lambda(3)-P phosphorus valence change. Complex 2 is shown to be one of the most efficient pre-catalysts for ketone hydrogenation in the Mn-I series reported to date (TON up to 6200).

A novel 2-thiopyrimidine/chalcone hybrid was designed, synthesised, and evaluated for their cytotoxic activities against three different cell lines, K-562, MCF-7, and HT-29. The most active cytotoxic derivatives were 9d, 9f, 9n, and 9p (IC50=0.77-1.74 mu M, against K-562 cell line), 9a and 9r (IC50=1.37-3.56 mu M against MCF-7 cell line), and 9a, 9l, and 9n (IC50=2.10 and 2.37 mu M against HT-29 cell line). Compounds 9a, 9d, 9f, 9n, and 9r were further evaluated for their cytotoxicity against normal fibroblast cell line WI38. Moreover, STAT3 and STAT5a inhibitory activities were determined for the most active derivatives 9a, 9d, 9f, 9n, and 9r. Dual inhibitory activity was observed in compound 9n (IC50=113.31 and 50.75 mu M, against STAT3 and STAT5a, respectively). Prediction of physicochemical properties, drug likeness score, pharmacokinetic and toxic properties was detected.
