The cationic organotin cluster [t-Bu2Sn(OH)(H2O)](2)(2+)2OTf(-) is easy to prepare and stable in air. The catalytic activity of [t-Bu2Sn(OH)(H2O)](2)(2+)2OTf(-) as a neutral organotin Lewis acid catalyst is probed through the one-pot three-component syntheses of 5-substituted 1H-tetrazoles from aldehydes, hydroxylamine hydrochloride and sodium azide, and of 2,4,6-triarylpyridines from aromatic aldehydes, substituted acetophenones and ammonium acetate. The reactions proceed well in the presence of 1 mol% of [t-Bu2Sn(OH)(H2O)](2)(2+)2OTf(-) in water and provide the corresponding 5-substituted 1H-tetrazoles and 2,4,6-triarylpyridines in good to excellent yields. The method reported has several advantages such as the catalyst being neutral, low catalyst loading and use of water as a green solvent.

This contribution introduces poly(2-oxazoline)-based shell cross-linked micelles (SCMs) as nanoreactors to realize one-pot redox-driven deracemizations of secondary alcohols in aqueous media. TEMPO and Rh-TsDPEN moieties are spatially positioned into the hydrophilic corona and the hydrophobic micelle core, respectively. TEMPO catalyzes the oxidation of racemic secondary alcohols into ketones, while Rh-TsDPEN catalyzes the asymmetric transfer hydrogenation (ATH) of these ketones to afford enantioenriched secondary alcohols. Both catalysts, the Rh-TsDPEN complex and TEMPO, are incompatible with each other and the SCMs are designed to provide indispensable catalyst site isolation. Kinetic studies show that the SCMs enhance the reactivity of the immobilized catalysts, in comparison to those for the unsupported analogues under the same reaction conditions. Our nanoreactors can perform deracemizations on a broad range of secondary alcohol substrates and are reusable in a continuous manner while maintaining high activity.

An efficient Ni(ClO4)(2)center dot 6H(2)O-promoted amidoalkylation re-action for the synthesis of 3-substituted isoindolinones involving various gamma-hydroxy lactams and nucleophiles has been successfully developed. The transformation proceeds with both carbon (ketones and arenes) and heteroatom (alcohols, thiols, and amines) nucleophiles and in both intermolecular and intramolecular manners. The prominent features of the present strategy are wide substrate scope, excellent group tolerability, and moderate to good yields (up to 96% yield). The present strategy is also characterized by remarkable superiority over the current synthetic methods. Furthermore, the reaction could be scaled up to the multigram scale.

Non-solvent and non-additive oxidation of secondary benzylic C-H bonds to aromatic ketones utilizing simple metalloporphyrins as catalysts and O-2 was investigated systematically. Based on systematical studies on reaction parameters, such as the structures of porphyrins, the types of central metals, the amount of catalyst, the pressure of oxygen, and the temperature, most aromatics with secondary benzylic C-H had been converted efficiently and selectively to their corresponding aromatic ketones catalyzed by the optimized metalloporphyrin catalyst T(2,3,6-triCl)PPCo. And the selectivity towards aromatic ketones reached up to 80 %-95 % with acceptable conversions in lower catalyst-loading (2.4 x 10(-3)%, mol/mol). The highest selectivity was achieved for substrate 1,2,3,4-tetrahydronaphthalene with the selectivity of 95.0 % in the conversion of 46.3 %. The superior catalytic performance of T(2,3,6-triCl)PPCo could be mainly ascribed to its excellent plane structure, superior ability for electron transfer and low positive charge around the central metal. All of above properties promoted the formation of catalytic active species high-valence cobalt-oxo complexes, and facilitated the approach of substrates to the catalytic active centers. This work presented an optimized balance among higher selectivity, milder conditions, lower catalyst-loading, and simpler catalysts compared with current documents, which was not only an efficient, practical and significant strategy to functionalize the widely available aromatics possessing secondary benzylic C-H with high efficiency and selectivity under milder conditions, but also an important instance in the effective functionalization and utilization of other C-H bonds employing optimized catalytic systems based on metalloporphyrins.

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.

Cost-effective and efficient photocatalysis are highly desirable in chemical synthesis. Here we demonstrate that readily prepared suspensions of APbBr(3) (A = Cs or methylammonium (MA)) type perovskite colloids (ca. 2-100 nm) can selectively photocatalyze carbon-carbon bond formation reactions, i.e., alpha-alkylations. Specifically, we demonstrate alpha-alkylation of aldehydes with a turnover number (TON) of over 52,000 under visible light illumination. Hybrid organic/inorganic perovskites are revolutionizing photovoltaic research and are now impacting other research fields, but their exploration in organic synthesis is rare. Our low-cost, easy-to-process, highly efficient and bandedge-tunable perovskite photocatalyst is expected to bring new insights in chemical synthesis.

Integrated continuous manufacturing has emerged as a promising device for the rapid manufacturing of active pharmaceutical ingredients (APIs). We herein report a newly designed continuous flow micro-total process system platform for the rapid manufacturing of celecoxib, a selective nonsteroidal anti-inflammatory drug. This approach has been proven generally for the synthesis of several alkyl and aryl substituted pyrazoles. In order to minimize the tedious work-up process of potential reaction intermediates/products, we have developed a continuous flow extraction and separation platform to carry out the entire reaction sequence resulting in a short residence time with good yield. The present process was further extended to gram scale synthesis of the COX-2-related API, viz. celecoxib, in the continuous flow process.

An unprecendented chiral sulfide catalyzed desymmetrizing enantioselective chlorination is disclosed. Various aryl-tethered diolefins and diaryl-tethered olefins afforded teralins and tricyclic hexahydrophenalene derivatives, respectively, bearing multiple stereogenic centers in high yields with excellent enantio- and diastereoselectivities. In contrast, the tertiary amine catalyst (DHQD)(2)PHAL led to a diastereomeric product. The products could be transformed into a variety of compounds, such as spiro-N-heterocycles.

A highly versatile and flexible copper nanoparticle (Cu(0) NPs) catalytic system has been developed for the controlled and selective transfer hydrogenation of nitroarene. Interestingly, the final catalytic product is strongly dependent on the nature of the hydrogen donor source. The yield of nitrobenzene reduction to aniline increased from 20% to an almost quantitative yield over a range of alcohols, diols and aminoalcohols. In glycerol at 130 degrees C aniline was isolated in 93% yield. In ethanolamine, the reaction was conveniently performed at a lower temperature (55 degrees C) and gave selectively substituted azobenzene (92% yield). Experimental studies provide support for a reaction pathway in which the Cu(0) NPs catalysed transfer hydrogenation of nitrobenzene to aniline proceeds via the condensation route. The high chemoselectivity of both protocols has been proved in experiments on a panel of variously substituted nitroarenes. Enabling technologies, microwaves and ultrasound, used both separately and in combination, have successfully increased the reaction rate and reaction yield.

A facile synthesis of a group of novel thiazole-pyrazolone hybrids and their investigation for angiotensin-converting enzyme (ACE) inhibition are reported in this study. These compounds were synthesized using a well-known approach, based on the condensation of ethyl acetoacetate with thiazolylhydrazines, and characterized by various spectroscopic and analytical techniques. The entire set of compounds displayed a moderate-to-excellent inhibitory activity against ACE. In particular, compound4iwas found to be the most potent ACE inhibitor and was further studied for cardioprotective effects against isoproterenol (ISO)-induced myocardial infarction (MI) in rats. Compound4iimproved the cardiac function and prevented cardiac injury induced by ISO in Sprague Dawley rats. The levels of oxidative stress and proinflammatory cytokines were also restored to near normal by4ias compared with the ISO group. In the Western blot analysis, compound4iprevented mitochondrial apoptosis after MI by downregulating the expression of cleaved caspase-3 and Bax, with the upregulation of Bcl-2, as compared with the ISO group.
