The aim of the study is to design and synthesis of a new series of potent anti-TB 1,2,4-triazol-1-yl-pyrazole based spirooxindolopyrrolizidines with their safety profile. A synergetic effect of ultrasonication and ionic liquid was shown successfully as a green methodology for the synthesis of title compounds 6a-t. These derivatives were obtained in shorter reaction time with good yields and well characterized by various spectroscopic methods, single-crystal X-ray diffraction (6f). The in vitro anti-tuberculosis activity for newly-synthesized derivatives has been screened against Mycobacterium tuberculosis. Among all, six compounds 6e, 6k, 6l, 6n, 6q and 6r exhibited equal potent activity compared to standard drug ethambutol (MIC: 1.56 mu g/mL) and another compound 6h exhibited outstanding activity (MIC: 0.78 mu g/mL) than the standard drug ethambutol. Cytotoxic nature of the anti-TB active compounds was evaluated against RAW 264.7 cells. The 6h, 6e, 6k, 6l, 6n, 6q and 6r exhibited lower toxicity which could be promising hits for anti-tuberculosis.

Ferredoxin:NADP(+) oxidoreductase from Plasmodium falciparum (PfFNR) catalyzes the NADPH-dependent reduction of ferredoxin (PfFd), which provides redox equivalents for the biosynthesis of isoprenoids and fatty acids in the apicoplast. Like other flavin-dependent electrontransferases, PfFNR is a potential source of free radicals of quinones and other redox cycling compounds. We report here a kinetic study of the reduction of quinones, nitroaromatic compounds and aromatic N-oxides by PfFNR. We show that all these groups of compounds are reduced in a single-electron pathway, their reactivity increasing with the increase in their single-electron reduction midpoint potential (E-7(1)). The reactivity of nitroaromatics is lower than that of quinones and aromatic N-oxides, which is in line with the differences in their electron self-exchange rate constants. Quinone reduction proceeds via a ping-pong mechanism. During the reoxidation of reduced FAD by quinones, the oxidation of FADH(.) to FAD is the possible rate-limiting step. The calculated electron transfer distances in the reaction of PfFNR with various electron acceptors are similar to those of Anabaena FNR, thus demonstrating their similar intrinsic reactivity. Ferredoxin stimulated quinone- and nitro-reductase reactions of PfFNR, evidently providing an additional reduction pathway via reduced PfFd. Based on the available data, PfFNR and possibly PfFd may play a central role in the reductive activation of quinones, nitroaromatics and aromatic N-oxides in P. falciparum, contributing to their antiplasmodial action.

The mode of asymmetric induction in an enantioselective intramolecular allylic substitution reaction catalyzed by a combination of palladium and a chiral phosphoric acid was investigated by a combined experimental and statistical modeling approach. Experiments to probe nonlinear effects, the reactivity of deuterium-labeled substrates, and control experiments revealed that nucleophilic attack to the pi-allylpalladium intermediate is the enantio-determining step, in which the chiral phosphate anion is involved in stereoinduction. Using multivariable linear regression analysis, we determined that multiple noncovalent interactions with the chiral environment of the phosphate anion are integral to enantiocontrol in the transition state. The synthetic protocol to form chiral pyrrolidines was further applied to the asymmetric construction of C-O bonds at fully substituted carbon centers in the synthesis of chiral 2,2-disubstituted benzomorpholines.

Selective hydrogenation of nitroarenes to arylamines is a great challenge because of the complicated mechanism and competitive hydrogenation of reducible functional groups. Isolated single-atomic site catalysts, benefitting from their uniform and well-defined catalytic sites, are promising to achieve high activity and selectivity. Herein, we prepared an isolated iron single-atomic catalyst supported on ordered mesoporous nitrogen-doped carbon (Fe-1/N-C). The as-prepared Fe-1/N-C showed excellent activity and tolerance for functional groups in the transfer hydrogenation of nitroarenes over hydrazine hydrate. Density functional theory calculations revealed that the single atomically dispersed, partially positively charged Fe atoms and the lowered energy barrier collectively contribute to the superior hydrogenation performances for nitroarenes.

We demonstrate a method to boost the photocatalysis of titania by constructing a core-shell structure. The crucial technique is to capsulate the titania nanoparticles by a sheath of nitrogen-doped carbon (TiO2@N-AC) with a thickness at 3.5-7.5 nm, which creates an exceptional effect to accelerate the catalytic hydrogenation of substituted nitroarenes with isopropanol as the hydrogen source under ultraviolet or visible-light irradiation. In the catalytic hydrogenation of various nitroarenes with substituted groups of -Cl, -F, -C-C, -C-O, and -C=N, TiO2@N-AC exhibits high conversions and selectivities to the corresponding functionalized anilines, even outperforming the catalysts containing noble metals. Mechanism study demonstrates that the TiO2@N-AC catalyst benefits the selective adsorption of the nitro group rather than other substituted groups, which efficiently avoids the undesirable side reactions. Importantly, the catalyst is stable and exhibits constant performances in the continuous recycling tests.

A copper(0)/PPh3-mediated cascade bisheteroannulation reaction of o-nitroalkynes with methylketoximes has been developed that provides viable access to a diverse range of pyrazo-fused pseudoindoxyl compounds. Synthetically useful functional groups including sensitive C-I bonds are compatible with this system. Mechanistic studies suggest a reaction cascade involving sequential PPh3-mediated deoxygenative cycloisomerization and copper-catalyzed [3 + 2] pyrazo-annulation.
