Catalytic reductions of carbonyl-containing compounds are highly important for the safe, sustainable, and economical production of alcohols. Herein, we report on the efficient transfer hydrogenation of ketones catalyzed by a highly potent Mn(I)-NHC complex. Mn-NHC 1 is practical at metal concentrations as low as 75 ppm, thus approaching loadings more conventionally reserved for noble metal based systems. With these low Mn concentrations, catalyst deactivation is found to be highly temperature dependent and becomes especially prominent at increased reaction temperature. Ultimately, understanding of deactivation pathways could help close the activity/stability-gap with Ru and Ir catalysts towards the practical implementation of sustainable earth-abundant Mn-complexes.

Zr-based metal-organic frameworks have been considered promising heterogeneous catalysts in various reactions. It has been proven that the defect sites in these frameworks, which result from deficiency of linkers, could act as the reaction active sites. In this work, microwave irradiation was used for rapid synthesis and increasing defects on Zr-6 clusters of metal-organic framework UiO-66. Powder X-ray diffraction, thermal gravimetric analysis, and N-2 sorption isotherms were performed to characterize and calculate the defect number in the framework. UiO-66 prepared by microwave method for a few minutes could reach 1.8 missing linkers per cluster. The material with acetic acid as a co-catalyst showed highly heterogeneous catalytic activity in the solvent-free heterocyclization of 2,2-disubstituted 2,3-dihydroquinazolin-4(1H)-ones from anthranilamide and ketones/aldehydes. The synthetic scheme consisted of zirconium cluster catalysed carbonyl group of anthranilamide to achieve the C-N propitious combination and succeeding ring closure process.

Efficient and mild reaction conditions for Wacker-type oxidation of terminal olefins of less explored homoallyl alcohols to beta-hydroxy-methyl ketones have been developed by using a Pd(ii) catalyst and MnO(2)as a co-oxidant. The method involves mild reaction conditions and shows good functional group compatibility along with high regio- and chemoselectivity. While our earlier system of PdCl2/CrO3/HCl produced alpha,beta-unsaturated ketones from homoallyl alcohols, the present method provided orthogonally the beta-hydroxy-methyl ketones. No overoxidation or elimination of benzylic and/or beta-hydroxy groups was observed. The method could be extended to the oxidation of simple terminal olefins as well, to methyl ketones, displaying its versatility. An application to the regioselective synthesis of gingerol is demonstrated.

Dementia is a cognitive disorder mostly associated with Alzheimer’s disease (AD) in addition to being seen in many other diseases of the central nervous system (CNS). The limited number of drugs is not sufficient to provide adequate improvement to increase the quality of life of patients suffering from this symptom; therefore, all treatment options should be evaluated in detail. In this study, new molecules, [2-(4-(2/3/4-substituted phenyl)piperazin-1-yl)-4-phenylthiazol-5-yl][3/4-substituted phenyl]methanone derivatives (1-44), were obtained and analyzed in terms of their anticholinesterase activities. Kinetic mode and molecular interactions were also evaluated. An enzyme inhibition study was undertaken on acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) using the Ellman method. Maestro program was used in molecular modeling studies. Forty-four compounds were evaluated on AChE and BChE enzymes at 10(-3) and 10(-4) concentrations. The inhibition concentrations were calculated as 0.268 mu M to 2.104 mu M for six compounds (4, 5, 16, 27, 37, and 38) on AChE. Compound 5 including the 4-methoxy substituent (IC50: 0.268 mu M) and compound 38 containing the 4-methoxy and 3-methyl substituents (IC50: 0.286 mu M) showed the highest AChE inhibitory activity. They were further examined in terms of hydrogen bonding with Arg296 and Ar-Ar interaction with Trp286. The activity of compound 5 was also assessed in mixed-type kinetic mode.

An array of arylnitro compounds with various functionality were treated with freshly-prepared aluminum amalgam in THE/water solution and resulted in the corresponding arylamines. The Al(Hg)-mediated reductions are relatively rapid with consumption of the amalgam and disappearance of starting material occurring over 20-30 min. The workup of the reductions involves only removal of the insoluble by-products by filtration followed by concentration. Only in some cases is chromatography required to secure the pure product. The desired arylamines are furnished in quantities of 25-100 mg, which in some cases, could be taken on to the next reaction without further purification. Reductions of 4-nitrobenzyl derivatives of carbohydrates or nucleosides were selective in affording the corresponding 4-aminobenzyl products. To show applicability in click chemistry, selected aminobenzyl products are directly azidated to yield products that were then used in click reactions to afford the corresponding 1,2,3-triazoles.

Replication protein A (RPA) is the major human single stranded DNA (ssDNA)-binding protein, playing essential roles in DNA replication, repair, recombination, and DNA-damage response (DDR). Inhibition of RPA-DNA interactions represents a therapeutic strategy for cancer drug discovery and has great potential to provide single agent anticancer activity and to synergize with both common DNA damaging chemotherapeutics and newer targeted anticancer agents. In this letter, a new series of analogues based on our previously reported TDRL-551 (4) compound were designed to improve potency and physicochemical properties. Molecular docking studies guided molecular insights, and further SAR exploration led to the identification of a series of novel compounds with low micromolar RPA inhibitory activity, increased solubility, and excellent cellular up-take. Among a series of analogues, compounds 43, 44, 45, and 46 hold promise for further development of novel anticancer agents.

In the present work, four types of heterocyclic core-based polybenzoxazine matrices (HC-PBZ) developed based on pyridine, thiophene, and thiazole and their molecular structure, thermal, flame-retardant and luminescent properties were studied and discussed. The heterocyclic core-based benzoxazine monomers (HC-BZ) were synthesized using two types of phenols (phenol, and 4-hydroxyphenylacetonitrile), and two types of heterocyclic diamines [2,6-Bis-(4-aminophenyl)-4-thiophen-2-yl-pyridine (BATP) and 4-(2-methylthiazol-5-yl)-2,6-bis-(4-aminophenyl)-pyridine (BAMTP)] with formaldehyde through Mannich reaction. The structure of the four HC-BZ monomers was confirmed by various spectral analysis such as Fourier-transform infrared spectroscopy (FTIR), and Nuclear magnetic resonance spectroscopy ((HNMR)-H-1 and (CNMR)-C-13). All the four HC-BZ monomers have the maximum range of curing temperature (T-p) between 252 and 267 degrees C. Data resulted from the thermal studies indicate that the HC-PBZ exhibits better T-g,T- thermal stability and flame-retardant properties. Among the four HC-PBZ systems the thiazole based system possesses the higher value of T-g of 268 degrees C and thermal stability when compared to those of other matrices. It was also observed that the HC-BZ monomers and HC-PBZ polymers exhibit a photoluminescent (PL) emission range between 441-445 and 414-417nm, respectively. Overall, it seems that the thiazole and thiophene based HC-PBZ can be considered as competitive materials for luminescent applications with high thermal and flame-retardant properties.
