A series of novel (E)-4-oxo-2-crotonamide derivatives were designed and synthesized to find potent antituberculosis agents. All the target compounds were evaluated for their in vitro activity against Mycobacterium tuberculosis H(37)Rv(MTB). Results reveal that 4-phenyl moiety at part A and short methyl group at part C were found to be favorable. Most of the derivatives displayed promising activity against MTB with MIC ranging from 0.125 to 4 mu g/mL. Especially, compound IIIa16 was found to have the best activity with MIC of 0.125 mu g/mL against MTB and with MIC in the range of 0.05-0.48 mu g/mL against drug-resistant clinical MTB isolates.

In the field of catalysis, material scientists pay much attention to tuning the activity and chemoselectivity of metal nanoparticles. Herein, we design and successfully synthesize a series of Co NPs which show high performance on hydrogenation of nitroarenes with both activity and chemoselectivity. Co-0.15@C/PC preferentially activates the -C=O bond over -NO2 in water with ammonia borane (AB); however, when the hydrogen source is changes to hydrazine hydrate (HH), the results are the opposite. The Co-based catalyst exhibits exceptionally high catalytic activity (with a TOF value of 10512 h(-1), which is approximately 100 times than the akin catalysts) and chemo-selectivity for the hydrogenation of nitro compounds under mild conditions. Additionally, the catalyst can be separated easily by a magnet and shows prominent stabilit, which means that it can be reused for at least 10 cycles.

A convenient access toward novel fluoroionophores based on 1-(2-pyridyl)-4-styrylpyrazoles (PSPs) substituted at position 3 with donor or acceptor aryl groups is reported. The synthesis proceeds in two steps: the first one via Wittig olefination of the appropriate 4-formylpyrazole and then Mizoroki-Heck coupling to yield the desired products in an overall yield of up to 69%. Photophysical properties of products (4-styryl) and their intermediates (4-vinyl) were explored, finding that they have strong blue-light emission with high quantum yields (up to 66%) due to ICT phenomena. The 3-phenyl PSP was studied as a turn-off fluorescent probe in metal ion sensing, finding a high selectivity to Hg2+ (LOD = 3.1 x 10(-7)M) in a process that could be reversed with ethylenediamine. The sensing mechanism and binding mode of the ligand to Hg2+ were established by HRMS analysis and H-1 NMR titration tests.

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.

An efficient synthetic method of medicinally important chalcone-derived heteroaromatics was proposed, which comprised of conjugate addition of ethyl acetoacetate to chalcones, followed by Mn-III/Co-II-catalyzed oxidative deacetylation. Paal-Knorr reactions of the resulting 1,4-dicarbonyl compounds containing various phenyl substituents produced the corresponding 2-carboethoxy-3,5-diphenyl furans, pyrroles, and thiophenes. The scope, mechanism, and electronic requirements for the phenyl substituents of chalcones in the key radical-medicated deacetylation reaction were fully elucidated. Antibacterial activities of the 21 chalcone-derived heteroaromatics were screened for Escherichia coli, Staphylococcus aureus, and Acinetobacter baumannii. The parent pyrrole 5 a showed most effective inhibition for E. coli and one third of the heteroaromatics exhibited significant inhibition for S. aureus at the concentration of 64 mu g/mL.

In the present investigation, an alluring green PEG-400 mediated one-pot synthesis of novel 2-(2-hydrazinyl)thiazole derivatives from 1,2,6,7-tetrahydro-8H-indeno[5,4-b]furan-8-one has been unveiled via a novel synthetic pathway. The application of PEG in organic reactions as a reaction media is one of the fantastic tools of green chemistry as reactions can be carried out under generous conditions limiting environmental peril and chemical waste. PEG-400 is recognized as a low-cost, non-flammable, environmentally benign, recyclable, and richly available green solvent. A series of novel 2-(2-hydrazineyl)thiazole derivatives have been synthesized in good to excellent yield by using the green capability of PEG-400 solvent. These newly synthesized compounds were tested for their antimicrobial and antioxidant activities. The results revealed that these compounds show good activities compared with the standard. Additionally, all the synthesized compounds exhibit negligible cytotoxicity as compared to the positive control. The structures of all novel compounds reported herein are established using FT-IR, H-1 NMR, C-13 NMR, D2O exchange experiment and HRMS techniques.

The iron oxide was successfully supported on activated clay/carbon through an experimentally viable protocol for both hydrations of nitrile to amide and reduction of nitro compounds to amines. The as-prepared catalyst has been extensively characterised by XPS, SEM-EDX, TEM, TGA, BET surface area measurements and powdered X-ray diffraction (PXRD). A wide variety of substrates could be converted to the desired products with good to excellent yields by using water as a green solvent for both the reactions. The catalyst was recyclable and reusable up to six consecutive cycles without compromising its catalytic proficiency.
