A facile and general synthesis of 2,4,6-triaryl pyrimidines has been developed. It involves a one-pot [2+1+1+1+1] pseudo five-component annulation of one methyl ketone, two aldehydes and two NH4OAc catalyzed by TfOH. One C-C and four C-N bonds are formed during the oxidative annulation process. The reaction shows good tolerance of many important functional groups in air and produces only water as the coproduct, making this methodology a highly versatile alternative to the existing methods for structuring pyrimidine framework.

A series of metal-free N-doped carbon nanotubes (NCNTs) are synthesized using melanin or protoporphyrin IX as the dopant via a pyrolysis process. Multiwalled carbon nanotubes with various diameters are employed as the support, and their performance is compared with those of graphene and carbon black. The content of doped graphitic N is effectively controlled by varying the heating rate during pyrolysis. The obtained metal-free catalysts are employed to catalyze the hydrogenation of various nitroarenes under mild reaction conditions (2 MPa of H-2, 120 degrees C). Efficient and selective hydrogenation of 14 nitroarenes is achieved over NCNTs with outer diameters of <= 20 nm synthesized via pyrolysis of melanin at 800 degrees C. Graphitic N in the as-prepared NCNTs is found to play a key role in efficient hydrogenation. Kinetic data reveal that a zero-order reaction occurs on the NCNTs, and the apparent activation energy of 4-nitrophenol hydrogenation is as low as 35.69 kJ mol(-1). Recycling experiments indicate that the NCNTs have good stability and recyclability for hydrogenation of 4-nitrophenol. (c) 2019 Elsevier Ltd. All rights reserved.

An efficient and convenient method for the synthesis of various substituted pyrano[3,2-c]chromene-2,5-diones was developed via the I-2-promoted tandem cyclization of commercially available aryl methyl ketones and 4-hydroxycoumarins. Preliminary mechanism studies indicated that the reaction involved a consecutive iodination/Kornblum oxidation/annulation process. HI produced in the I-2-DMSO system acted as an important promoter, accelerating the annulation protocol. (C) 2019 Elsevier Ltd. All rights reserved.

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.

The ultraviolet (UV) absorption spectra of the supermolecular system involving silver nanoparticles-substituted N-(phenyl-ethylene)-anilines were investigated. Silver nanoparticles (AgNPs) and 77 kinds of substituted N-(phenyl-ethylene)-anilines ZArC (Me)NArY (ZPEAY, including 40 compounds 2-H-XPEAY without ortho-hydroxyl and 37 compounds 2-OH-XPEAY with ortho-hydroxyl) were prepared. The size of AgNPs was measured with transmission electron microscopy. To study the effect of substituents X and Y on the UV spectra of the supermolecular system of AgNPs-ZPEAY, the authors measured the UV absorption spectra of AgNPs, ZPEAY, and AgNPs-ZPEAY solutions. The experimental results show that (a) the size of AgNPs increases in AgNPs-ZPEAY solution compared with that in AgNPs solution, due to the absorption of ZPEAY molecules on the surface of AgNPs; (b) the UV absorption wavelength of ZPEAY changes in AgNPs-ZPEAY solution and there is a limitation for the wavelength shift (lambda (WSL)) between ZPEAY and AgNPs-ZPEAY system; (c) there is a quantitative correlation between the wavenumber Delta nu (WSL) of lambda (WSL) and the substituent constants (Hammett constant sigma and excited-state substituent constant sigma CCex) of substituents X and Y; (d) the intramolecular hydrogen bonding in 2-OH-XPEAY makes the Delta nu (WSL) a red shift in AgNPs-ZPEAY system.

A synergistic gold-iron (Au-Fe) catalytic system was developed for sequential alkyne hydration and vinyl Au addition to aldehydes or ketones. Fe(acac)(3) was identified as an essential co-catalyst in preventing vinyl Au protodeauration and facilitating nucleophilic additions. Effective C-C bond formation was achieved under mild conditions (room temperature) with excellent regioselectivity and high efficiency (1% [Au], up to 95% yields). The intramolecular reaction was also achieved, giving successful macrocyclization (16-31 ring sizes) with excellent yields (up to 90%, gram scale) without extended dilution (0.2 M), which highlights the great potential of this new crossed aldol strategy in challenging target molecule synthesis.

alpha-Glucosidase inhibition has been considered as an effective strategy for controlling the post-prandial hyperglycemia in diabetic patients. A series of novel isatin-pyrazole hybrids has been rationally designed, synthesized and characterized by different spectroscopic techniques. All of the synthesized compounds were evaluated for their alpha-glucosidase inhibitory potential using in vitro enzymatic assay. The tested compounds have exhibited potent alpha-glucosidase inhibition with IC50 values ranging from 3.26 +/- 0.25 to 32.33 +/- 1.08 mu M. Compound V7, having 3-nitro phenyl ring appended at pyrazole nucleus, has emerged as the most potent inhibitor among the series with an IC50 value of 3.26 +/- 0.25 mu M, which was approximately 146 fold more potent than the clinically used drug acarbose (IC50 = 478.07 +/- 1.53 mu M). Molecular docking studies were carried out to investigate the binding interactions of most active compounds with the active site of the enzyme. Further, in silico predictive pharmacokinetic parameters (ADME) and drug-like properties of the compounds were within the acceptable ranges. In vivo biological evaluations further supplemented the in vitro results.

A [3+1+1+1] cycloaddition was developed among 2-arylpropene, ketone and DMSO in the presence of K2S2O8. 2-arylpropene provides three carbons, ketone offers one carbon, and DMSO as dual carbon donor contributes two carbons to the six-membered carbocycle. It gave the cyclohexene motif and spirocyclohexene skeleton. Four C-C bonds formed in this process. Both propylene and ketone could be well tolerated and give the corresponding cyclohexene or spirocyclohexene motif in useful yields. Based on the controlled experiments, a possible mechanism was proposed.

An efficient additive-free manganese-catalyzed hydrogenation of nitriles to primary amines with molecular hydrogen is described. The pre-catalyst, a well-defined bench-stable alkyl bisphosphine Mn(I) complex fac-[Mn(dpre)(CO)(3)(CH3)] (dpre=1,2-bis(di-n-propylphosphino)ethane), undergoes CO migratory insertion into the manganese-alkyl bond to form acyl complexes which upon hydrogenolysis yields the active coordinatively unsaturated Mn(I) hydride catalyst [Mn(dpre)(CO)(2)(H)]. A range of aromatic and aliphatic nitriles were efficiently and selectively converted into primary amines in good to excellent yields. The hydrogenation of nitriles proceeds at 100 degrees C with a catalyst loading of 2 mol % and a hydrogen pressure of 50 bar. Mechanistic insights are provided by means of DFT calculations.
