Fifty one hydrazone derivatives of eugenol were designed and docked with 2NSD and 2X22 (enzymes of H37Rv strain) using Schrodinger v7.4. The selective ten hydrazone derivatives (4, 5, 11, 18, 30, 34, 35, 37, 42, and 45) of eugenol were synthesized via esterification, hydrazination and treatment with different aldehydes. Synthesized compounds were characterized by IR, H-1 NMR, and LCMS data. The compounds were evaluated for their antitubercular potential against H37Rv using microplate alamar blue assay (MABA). The study revealed that all synthesized compounds were significantly active at concentration 50 and 100 mu g/ml, whereas compound 11 exhibited activity at 25 mu g/ml. Present study showed that antitubercular activity of novel hydrazone derivatives of eugenol is strongly connected with the position of the substituent on aromatic aldehyde or ketones.

Two new sulfonated (SDA) and carboxylated (CDA) aromatic diamine-diol monomers were synthesized and applied to prepare thin-film composite (TFC) nanofiltration (NF) membranes with improved antifouling and performance properties. The interfacial polymerization method was used to make sulfonated and carboxylated TFC-NF membranes with reaction of trimesoyl chloride (TMC) in the organic phase with amine and hydroxyl agents in the aqueous phase. Herein, for the first time, a comparison between carboxylated and sulfonated TFC was carried out. Moreover, the probability of synergetic effect between these two synthetic monomers (CDA and SDA) and piperazine monomer was studied (the sulfonated monomer and piperazine showed a synergetic effect). The outcomes of flux recovery ratio (FRR), flux and contact angle showed that in the presence of newly synthesized monomers, membrane hydrophilicity considerably improved. The salt retention sequence for all membranes was Na2SO4 NaCl > CaCl2, which means all membranes had a negative charge. Among the five prepared TFC membranes (SDA, CDA, PIP, SDA/PIP, and CDA/PIP), the SDA/PIP showed the best salt rejection (97% Na2SO4) with flux (50 Lm(-2)h(-1)) and 91% FRR, at operating pressure of 10 bars. Although the SDA showed the highest permeability (62 Lm(-2) h(-1)) and FRR of 92%, it presented the lowest Na2SO4 rejection. The results indicated that mixing carboxylated monomers with PIP caused deterioration in properties, while mixing sulfonated monomer with PIP enhanced the performances of the related TFC. Better permeability of the membrane made by newly synthesized monomers is ascribed to the existence of strong hydrophilic sulfonic acid, carboxylic acid and terminal hydroxyls, and amine groups at polyamide top layer producing enhanced membrane antifouling properties.

TiO2 photocatalysis and peroxymonosulfate (PMS) oxidation can exhibit a good performance in ultraviolet light but a less activity in visible light (VL). Herein, the TiO2 nano-tubes arrays (TiO2NTAs) and PMS were combined to degrade bisphenol A (BPA) under VL irradiation. Surprisingly, about 94.6% of BPA was removed in TiO2 NTAs/PMS/VL system within 30 min, which was much higher than that of TiO2 NTAs/VL (20.1%) and PMS/VL (9.4%) systems. A series of spectroscopic characterizations and photoelectrochemical measurements confirmed the formation of PMS-TiO2 complex with VL response, which can be excited by VL to transfer electrons to the conduction band (CB) of TiO2 for activating PMS. The quenching tests and electron spin resonance (ESR) spectra indicated that SO4 center dot- and center dot OH were responsible for BPA degradation, and then the possible degradation pathways of BPA were proposed. Humic acid (HA) and chloride ions (Cl-) significantly enhanced the BPA degradation, while bicarbonate (HCO3-) and phosphate (H2PO4-) exhibited an inhibition effect. Moreover, TiO2 NTAs/PMS/VL system displayed an enhanced BPA degradation in tap water and drinking water compared with deionized water, and as an immobilization catalyst which fabricated on Ti plate, TiO2 NTAs exhibited excellent stability and separability without complex catalyst separation/recovery processes. We believe this work will provide a new insight of the VL-induced photocatalytic PMS activation in practical water treatment.

Transition-metal-catalyzed tandem Heck/carbonylation reaction has emerged as a powerful tool for the synthesis of structurally diverse carbonyl molecules, as well as natural products and pharmaceuticals. However, the asymmetric version was rarely reported, and remains a challenging topic. Herein, we describe a palladium-catalyzed asymmetric tandem Heck/carbonylation desymmetrization of cyclopentenes. Alcohols, phenols and amines are employed as versatile coupling reagents for the construction of multifunctional chiral bicyclo[3.2.1]octanes with one all-carbon quaternary and two tertiary carbon stereogenic centers in high diastereo- and enantioselectivities. This study represents an important progress in both the asymmetric tandem Heck/carbonylation reactions and enantioselective difunctionalization of internal alkenes. Tandem Heck/carbonylation reaction gives access to ubiquitous carbonyl molecules, however the asymmetric version is rarely studied. Here, the authors synthesize chiral bicyclo[3.2.1]octanes with a palladium-catalyzed asymmetric tandem Heck/carbonylation desymmetrization of cyclopentenes with alcohols, phenols and amines.

In the present study, we synthesized new functional hydrophobic acrylate monomers. The first monomer was based on 4-acetylacetophenone, and the other one was based on vanillin as a renewable resource. The starting material was reacted with acryloyl chloride for the formation of 4-acetylphenyl acrylate (APA) and 4-formyl-2-methoxyphenylacrylate (vanillin acrylate) or (VA), respectively. The chemical structures were deduced by H-1 NMR, 13C NMR, and FTIR. The effect of these monomers on the transition temperature or lower critical solution temperature of thermo-responsive N-isopropylacrylamide was achieved by the free radical polymerization of three different molar concentrations of both APA and VA with NIPAAm in solution and using 2,2 ‘ azobis(isobutyronitrile) (AIBN) as an initiator. The terpolymers were chemically evaluated. They have been also investigated by gel permission chromatography (GPC) for molecular weight and molecular weight distribution; the glass temperatures were determined by differential scanning calorimetry DSC; X-ray diffraction (XRD) was used for the extent of crystallinity; scanning electron microscopy was used (SEM) for surface morphology. The phase separation and lower critical solution temperature T-c were measured using two methods: UV-Vis spectroscopy for turbidity measurements and micro-DSC of the polymer solution. In the future, we will use these polymers in the bio-separation process and the formation of a responsive hydrogel. [GRAPHICS] .

Selective hydroxylation of different phenylboronic acids to phenols was successfully carried out by using Cu nanoparticles-enzyme hybrid catalysts in water and room temperature. Different Cu-enzyme hybrids containing Cu(II), Cu(I) and Cu(0) nanoparticles species respectively were tested on the monohydroxylation of phenylboronic acid under these mild conditions being hybrids containing Cu(0)NPs the best catalysts, with total selectivity and formation of phenol as unique product. Also, the addition of hydrogen peroxide or the increase of reaction temperature were tested but did not improved these results. The substrate scope was also demonstrated and the Cu(0)NPs hybrid showed excellent results in the monohydroxylation of differento-, m-, p-substituted phenylboronic acid with final yields >95 %. This catalyst showed excellent recyclability after 5 cycles of use.

Herein, a defective zeolite-carbon (CFR@HZSM-5) nanocomposite-supported nano-scale Pd catalyst (Pd/CFR@HZSM-5) was facilely synthesized for selective H2-free hydrodeoxygenation (HDO) of vanillin (VL) under mild conditions. The optimal Pd/CFR@HZSM-5(2:1) catalysts show excellent activity (the 99% yield to 2-methoxy-4-methylphenol) and high turnover frequency in polymethylhydrosiloxane at 60 degrees C. According to spectral analysis, there is an abundant carbon defect structure on the surface of the CFR@HZSM-5 nanocomposite, which can provide unique sites for capturing Pd metal nanoparticles (NPs) and serve as active sites to promote the adsorption of substrates. The stable and high-dispersion Pd NPs are fastened with carbon atoms in the vacancy defect through strong electronic metal-support interactions, which improved the activity of VL HDO up to four times higher than that of other catalysts under mild conditions. The unique high-dispersion Pd structure and abundant surface defects of Pd/CFR@HZSM-5 catalysts are significant features to brilliant catalytic activity for biomass-derived molecule HDO. Meanwhile, the abundance of acidic sites in the composite carrier catalyst replaces the use of acidic additives in previous catalytic systems. The optimal Pd/CFR@HZSM-5(2:1) catalysts showed good recovery even after five uses. The catalytic system was also applied for various biomass HDO models under mild conditions. This methodology opens new ideas for designing catalysts with high activity and high efficiency for selective HDO of biomass under green and mild conditions.

A visible-light-induced carbonylation of indoles with phenols for the synthesis of indole-3-carboxylates has been developed. The reaction proceeded via a radical carbonylation process in which elementary I-2 was used as an effective photosensitive initiator and, thus, avoided the use of transition metal catalysts. A series of different aryl indole-3-carboxylates were prepared in moderate to good yields. The broad applicability of this methodology was further highlighted by the late-stage functionalization of several phenol-containing natural products and pharmaceuticals.
