Benzylic alcohols have an important role in organic synthesis as target molecules of biological interest, which can be produced from the reduction of aromatic carbonyl substrates. In this work, the sonoelectrocatalytic hydrogenation (SECH) of aryl ketones was studied in water. The ultrasonic irradiation was carried out at frequency of 20 kHz +/- 500 Hz with a cylindrical titanium probe (MS 73 microtip; Ti-6AI-4V alloy; 3.0 mm diameter; Pacoustic- = 2.11 W). The results showed that the ultrasound irradiation enhances the mass-transport of the substrates from the bulk solution to the electrode surface, increasing the substrate availability to react with the adsorbed H, leading to higher yields. Regarding the electrode material, the following hydrogenation yields of a group of acetophenones was observed: Cu (79.0 +/- 1.5%) > Ni (73.0 +/- 2.0%) approximate to Fe/Ni (72.0 +/- 1.7%) > graphite (69.0 +/- 1.7%) > Fe (67.5 +/- 2.3%). The SECH presented a slight variation in the reactivity of some reagents, and its behaviour depends on the catalytic nature of the electrode support. Besides the lower overpotential and higher exchange current density of the graphite, it was surprisingly active under ultrasound irradiation, showing higher yields and current efficiencies than others electrocatalytic hydrogenation (ECH) procedures. The ultrasound irradiation decreases more than 6-folds the energy consumption of the ECH method, making it an effective and inexpensive way to produce alcohols from the respective aryl ketones in water.

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.

Herein, we present a robust and eco-friendly dynamic kinetic resolution (DKR) protocol for secondary alcohols using a combined heterogeneous catalytic CAL-B/VOSO4 system at 50 degrees C in the relatively green solvent heptane. This catalytic system is active and chemo- and enantioselective for up to 5 cycles. A set of 13 aromatic and heteroaromatic secondary alcohols were evaluated to determine the substrate scope. The performance of the combined CAL-B/VOSO4 system was improved by employing a low-cost, homemade Teflon tube to compartmentalize the catalysts in one-pot conditions, making this system for up to 8 reaction cycles.

Switchable selective hydrogenation among the groups in multifunctional compounds is challenging because selective hydrogenation is of great interest in the synthesis of fine chemicals and pharmaceuticals as a result of the importance of key intermediates. Herein, we report a new approach to highly selectively (>99%) reducing C=X (X = O, N) over the thermodynamically more favorable nitro groups locating the substrate in a metal-organic capsule containing NADH active sites. Within the capsule, the NADH active sites reduce the double bonds via a typical 2e(-) hydride transfer hydrogenation, and the formed excited-state NAD(+) mimics oxidize the reductant via two consecutive 1e(-) processes to regenerate the NADH active sites under illumination. Outside the capsule, nitro groups are highly selectively reduced through a typical 1e(-) hydrogenation. By combining photoinduced 1e(-) transfer regeneration outside the cage, both 1e(-) and 2e(-) hydrogenation can be switched controllably by varying the concentrations of the substrates and the redox potential of electron donors. This promising alternative approach, which could proceed under mild reaction conditions and use easy-to-handle hydrogen donors with enhanced high selectivity toward different groups, is based on the localization and differentiation of the 2e(-) and 1e(-) hydrogenation pathways inside and outside the capsules, provides a deep comprehension of photocatalytic microscopic reaction processes, and will allow the design and optimization of catalysts. We demonstrate the advantage of this method over typical hydrogenation that involves specific activation via well-modified catalytic sites and present results on the high, well-controlled, and switchable selectivity for the hydrogenation of a variety of substituted and bifunctional aldehydes, ketones, and imines.

The ketones was successfully prepared from secondary alcohols using 9-azabicyclo[3.3.1]nonane-N-oxyl (ABNO) as the catalyst and 2,6-lutidine as the base in acetonitrile solution. The electrochemical activity of ABNO for oxidation of 1-phenylethanol was investigated by cyclic voltammetry, in situ Fourier transform infrared spectroscopy (FTIR) and constant current electrolysis experiments. The resulting cyclic voltammetry indicated that ABNO exhibited much higher electrochemical activity when compared with 2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPO) under the similar conditions. A reasonable reaction mechanism of the electrocatalytic oxidation of 1-phenylethanol to acetophenone was proposed. In addition, a series of secondary alcohols could be converted to the corresponding ketones at room temperature in 80-95% isolated yields.

With the aim to discover novel, efficient and selective inhibitors of human alkaline phosphatase and nucleotide pyrophosphatase enzymes, two new series of pyrazolyl pyrimidinetriones (PPTs) (6a-g) and thioxopyrimidinediones (PTPs) (6h-n) were synthesized in good chemical yields using Knoevenagel condensation reaction between pyrazole carbaldehydes (4a-g) and pharmacologically active N-alkylated pyrimidinetrione (5a) and thioxopyrimidinedione (5b). The inhibition potential of the synthesized hybrid compounds was evaluated against human alkaline phosphatase (h-TNAP and h-IAP) and ectonucleotidase (h-NPP1 and h-NPP3) enzymes. Most of the tested analogs were highly potent with a variable degree of inhibition depending on the functionalized hybrid structure. The detailed structure-activity relationship (SAR) of PPT and PTP derivatives suggested that the compound with unsubstituted phenyl ring from PPT series led to selective and potent inhibition (6a; IC50= 0.33 +/- 0.02 mu M) of h-TNAP, whereas compound 6c selectively inhibited h-IAP isozyme with IC50 value of 0.86 +/- 0.04 mu M. Similarly, compounds 6b and 6h were identified as the lead scaffolds against h-NPP1 and h-NPP3, respectively. The probable binding modes for the most potent inhibitors were elucidated through molecular docking analysis. Structure-activity relationships, mechanism of action, cytotoxic effects and druglikeness properties are also discussed.

Selective hydrogenation of nitro compounds requires highly active and less expensive materials as a heterogeneous catalyst. As a good candidate, the Ni-Au alloy nanoparticles (NPs) have been synthesized by simple in-situ reduction method, which was loaded to the active carbon with 10 wt % loading amount. The Ni-Au/C catalyst shows superior catalytic performance for hydrogenation of nitro compounds with 100% conversion and selectivity without any by-products, which also indicates good recycle performance for several times use. The prepared catalyst not only reduces the usage amount of noble metal, but also keeps the high catalytic activity, which is a promising catalyst for industry applications. (C) 2019 Elsevier B.V.
