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.

The applications of a new supported tribromide reagent based on poly(vinylbenzyltrimethylammonium hydroxide) resin (Amberlite 717) were reported. This supported tribromide resin was used directly in alpha-bromination and alpha-bromoacetalization of acetophenones without any other catalyst under mild conditions. The effects of solvents and the amount of the supported tribromide resin on the reactions were investigated. Under the optimal conditions, most of alpha-bromo and alpha-bromoacetal of acetophenones were selectively obtained in excellent yields. [GRAPHICS] .

The reaction of LH [L = {(ArNH)(ArN)-C=N-C=(NAr)(NHAr)}; Ar =2,6-Et-2-C6H3] with a commercially available alane amine adduct (H3Al center dot NMe2Et) in toluene resulted in the formation of a conjugated bis-guanidinate (CBG)-supported aluminum dihydride complex, i.e., LAIH(2) (1), in good yield. The new complex has been thoroughly characterized by multinuclear magnetic resonance, IR, mass, and elemental analyses, including single-crystal structural studies. Further, we have demonstrated the aluminum-catalyzed hydroboration of a variety of nitriles and alkynes. Moreover, aluminum-catalyzed hydroboration is expanded to more challenging substrates such as alkene, pyridine, imine, carbodiimide, and isocyanides. More importantly, we have shown that the aluminum dihydride catalyzed both intra- and intermolecular chemoselective hydroboration of nitriles and alkynes over other reducible functionalities for the first time.

A series of novel mono- and binuclear arene-ruthenium(H) complexes [(p-cym)Ru(L)Cl] containing 11H-indeno [1,2-b]quinoxalin-11-one derivatives or tryptanthrin-6-oxime were synthesized and characterized by X-ray crystallography, IR, NMR spectroscopy, cyclic voltammetry, and elemental analysis. Theoretical calculations invoking singlet state geometry optimiza-tion, solvation effects, and noncovalent interactions were done using density functional theory (DFT). DFT calculations were also applied to evaluate the electronic properties, and time-dependent DFT was applied to clarify experimental UV-vis results. Cytotoxicity for cancerous and noncancerous human cell lines was evaluated with cell viability MTT assay. Complexes demonstrated a moderate cytotoxic effect toward cancerous human cell line PANC-1. The catalytic activity of the complexes was evaluated in transfer hydrogenation of aryl ketones. All complexes exhibited good catalytic activity and functional group tolerance.

Imidazolin-2-iminato hafnium complexes of the type [(Im (R) N)Hf(CH2Ph)(3)] were synthesized (Im(tBu)N = 1,3-di-tert-butylimidazolin-2-iminato); Im(Dipp)N = 1,3-bis(2,6-diisopropylphenyl)-imidazolin-2-iminato. The complexes were crystallized and structurally characterized. Despite the oxophilicity of the hafnium center, both hafnium complexes were catalytically active in the hydroboration of aldehydes, ketones, and carbodiimides. Herein, we present the influence of different substrates bearing electron-withdrawing or electron-donating groups on the catalytic reactions. Based on stoichiometric reaction in each process, plausible mechanistic scenarios are presented.

The latter was treated with excess hydrazine hydrate, and the resulting tetrahydrazide was converted to tetrakis1,2,4-triazolyl derivative via cyclization with ethanolic potassium hydroxide, carbon disulfide, and hydrazine hydrate. In the final stage, cyclocondensation with substituted chalcones afforded the target products. The structure of the newly synthesized compounds was confirmed by elemental analyses and FT-IR and NMR spectra, and their antimicrobial activities against some bacterial and fungal strains were estimated by the disc diffusion method.

Hydrofunctionalization, the direct addition of an X-H (e.g., X=O, N) bond across an alkene, is a desirable strategy to make heterocycles that are important structural components of naturally occurring molecules. Described here is the design and discovery of donor-acceptor-type platinum catalysts that are highly effective in both hydroalkoxylation and hydroamination of unactivated alkenes over a broad range of substrates under mild conditions. A number of alkene substitution patterns are accommodated, including tri-substituted, 1,1-disubstituted, (E)-disubstituted, (Z)-disubstituted and even mono-substituted double bonds. Detailed mechanistic investigations suggest a plausible pathway that includes an unexpected dissociation/re-association of the electron-deficient ligand to form an alkene-bound donor-acceptor-type intermediate. These mechanistic studies help understand the origins of the high reactivity exhibited by the catalytic system, and provide a foundation for the rational design of chiral catalysts towards asymmetric hydrofunctionalization reactions. The direct addition of an O-H (hydroalkoxylation) or an N-H (hydroamination) bond across an alkene is a useful strategy to access biologically relevant heterocycles. Here, the authors report donor-acceptor-type platinum catalysts that are effective for both hydroalkoxylation and hydroamination of unactivated alkenes, with broad substrate scope and use of mild conditions.

As the global need for drugs getting increases, the necessity of novel and effective drugs are the need of the day. Pyrazoles are one of the active molecules in novel drug discovery. The present study deals about the synthesis of precursors 4-(4-fluorophenyl)-6-isopropyl-2-(methylsulfonyl) pyrimidine-5-carbohydrazides (3a-m) from methyl- 4-(4-fluorophenyl)-6-isopropyl-2-(methyl sulfonyl) pyrimidine-5-carboxylate (2) by treating with substituted acetophenone. Further, Vilsmeier-Haack reaction of compounds 3a-m at 70 degrees C for 8-10 hrs gave novel pyrazole carbaldehyde derivatives (4a-m) in good yield. Biological properties like antioxidant, anti-breast cancer and anti-inflammatory of newly synthesized compounds (4a-m) were determined. The enzymes Cyclooxygenase-2 and Phosphoinositide-3-Kinase are most responsible for the corresponding diseases such as inflammation and breast cancer respectively. In order to examine the interaction between these two enzymes and our synthesized compounds 4a-m, molecular docking study was carried out. From the results, few compounds of 4a-m were found to have anti-inflammatory properties by showing excellent COX-2 inhibition and HRBC membrane stabilization properties. ADMET prediction results were also valuable to screen the most effective pyrazole derivatives to establish them as future COX-2 inhibitors or anti-inflammatory drugs.

The Pd-catalyzed decarboxylation and dual C(sp(3))-H bond functionalization approaches have been described for the preparation of symmetrical and unsym-metrical 2,4-diarylpyridines. The developed transformations were realized using nonactivated aromatic ketones and amino acids as C-N sources. The efficacy of the catalyst and reagent combination drives the transformation toward the formation of desired products with high yields and selectivity. The described reaction conditions have seduced the self-reaction of phenylalanine via [2 + 2 + 2] cycloaddition and minimized the formation of 3,5-phenylpyridine as a side product, whereas using glycine as a C-N source, the corresponding 2,6-diarylpyridines were formed as minor products.
