New 1,5-diaryl-3-(pyridin-4 ‘-yl)pentane-1,5-diones were synthesized via the tandem reaction of pyridin-4-carbaldehyde with methyl (aryl) ketones in the presence of sodium hydride. The treatment of the diketones with ammonium acetate resulted in heterocyclization to 2,6-diaryl-4-(pyridin-4 ‘-yl)pyridines.

Development of porous heteroatom-doped carbon materials from plant biomass is of great significance for various applications in environment, energy conversion and catalysis process. However, the different natures of carbon materials derived from the leaf, stem and root of the same plant biomass are rarely reported. Herein, we synthesized porous carbon materials from the leaf, stem and root of amaranth respectively by pyrolysis without any activation treatment. Detailed characterizations indicated that these three carbon materials all had nitrogen, sulfur doped atoms and similar degree of graphitization, but showed distinct differences in the pore structures and surface compositions. We suggested these differences were contributed by the different contents of ashes, vascular bundles and proteins in different parts. When used as metal-free carbocatalysts for the oxidation of aromatic hydrocarbons, stem-derived carbon (SDC-A) exhibited the highest catalytic performance due to its high surface area, profitable pore volume and rich doped heteroatoms. Moreover, the carbocatalysts derived from the leaf, stem and root of pumpkin vine and coriander showed similar activity differences in oxidation of aromatic alkanes, implying the present results have a certain extent generality, and provide a new guidance for preparing carbon materials from plant biomass.

An amine-functionalized metal organic framework (MOF) was used as highly efficient and recyclable heterogeneous catalyst for Knoevenagel condensation of various aromatic aldehydes and ketones in ethanol. The catalytic efficiency was demonstrated by the high conversion of the reactants with 100% selectivity under microwave (mu W) irradiation, while dramatically reduced the reaction time as compared to the conventional heating method. Importantly, the MOF maintained its structural integrity after catalytic reactions and it could be reused several times without remarkable loss of activity.

Porous nanoreactors demonstrate immense potential for applications in heterogeneous catalysis due to their excellent mass-transfer performance and stability. The design of a simple, universal strategy for fabricating nanoreactor catalysts is of significance for organic transformation. In this study, a nanoreactor with a hierarchical mesoporous yolk-shell structure was successfully prepared by the high-temperature carbonization of a ZIF-67@polymer composite. The core of the resultant Co@ZDC@mC material comprised Co NPs anchored in the ZIF-67-derived carbon framework, while the shell comprised resin-polymer-derived mesoporous carbon. The as-obtained Co@ZDC@mC-700 catalyst enriched reactants, efficiently catalyzed the reaction in the core, and permitted the desorption of the product from the nanoreactor. In the catalytic reduction of nitrobenzene with N2H4.H2O, Co@ZDC@mC-700 exhibited superior catalytic efficiency (TOF=1136.3 h(-1)). In addition, Co@ZDC@mC-700 exhibited excellent performance for the catalytic reduction of various functionalized nitroarenes, as well as good reusability and recyclability. Hence, a simple, useful approach for fabricating a metal-organic-framework-derived non-noble metal-based yolk-shell nanoreactor for effective catalytic transformation is proposed.

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.

A strategy for heterogeneous copper(I) mesoporous silica [Cu(I)-SBA-15] mediated catalytic reduction has been developed for the reduction of various nitroarenes in excellent yields. In addition to alcothermal strategy, other strategies have been attempted for the preparation of Cu(I) substituted mesoporous silica, however, the desired oxidation state is obtained only through alcothermal strategy. The crystalline phases and oxidation state of synthesized materials were characterized by XRD and XPS measurements and tested for catalytic reduction of nitroarenes. Among the tested materials, the best catalytic reduction of nitroarenes with an excellent substrate scope and good catalytic reusability was established by Cu(I)-SBA-15 material. The reduction kinetics and the controlled experimental studies reveal that the reaction proceeds through pseudo-first-order kinetics and nitrosobenzene intermediate pathway.

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.

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.

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.

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.
