A pyrimidine moiety exhibiting a wide range of pharmacological activities has been employed in the design of privileged structures in medicinal chemistry. To prepare libraries of novel heterocyclic compounds with potential biological activities, a series of novel 2-(pyridin-2-yl) pyrimidine derivatives were designed, synthesized and their biological activities were evaluated against immortalized rat hepatic stellate cells (HSC-T6). Fourteen compounds were found to present better anti-fibrotic activities than Pirfenidone and Bipy55 ‘ DC. Among them, compounds ethyl 6-(5-(p-tolylcarbamoyl)pyrimidin-2-yl)nicotinate (12m) and ethyl 6-(5-((3,4-difluorophenyl)carbamoyl)pyrimidin-2-yl)nicotinate (12q) show the best activities with IC50 values of 45.69 mu M and 45.81 mu M, respectively. Furthermore, the study of anti-fibrosis activity was evaluated by Picro-Sirius red staining, hydroxyproline assay and ELISA detection of Collagen type I alpha 1 (COL1A1) protein expression. Our study showed that compounds 12m and 12q effectively inhibited the expression of collagen, and the content of hydroxyproline in cell culture medium in vitro, indicating that compounds 12m and 12q might be developed the novel anti-fibrotic drugs.

Aryl and heteroaryl chiral carbinols are useful precursors in the synthesis of drugs. Lactobacillus paracasei BD87E6, which is obtained from a cereal based fermented beverage, was investigated as whole cell biocatalyst for the bioreduction of different ketones (including aromatic, hetero-aromatic and fused bicyclic ketone) into chiral carbinols, which can be used as a pharmaceutical intermediate. The study shows that bioreduction of aryl, heteroaryl and fused bicyclic ketone (1-5) to their corresponding chiral carbinols (1a-5a) in excellent enantioselectivity (>99%) with high yields. This study gave the first example for an enantiopure production of (S)-6-chlorochroman-4-ol (3a), which has many antioxidant activity, by a biological method. For asymmetric bioreduction of other prochiral ketones, these results open way to use of L. paracasei BD87E6 as biocatalysts. Also, the present process shows a hopeful and alternative green synthesis for the production of enantiopure carbinols in a mild, inexpensive and environmentally friendly process.

We have developed a protocol for the Cu/Ni-catalyzed cyanomethylation of alkenes with acetonitrile for the synthesis of beta,gamma-unsaturated nitriles. This is the first example of a direct coupling of the alkene sp(2) C-H bond and the acetonitrile sp(3) C-H bond for the preparation of beta,gamma-unsaturated nitriles. Acetonitrile, an inexpensive and stable solvent, is demonstrated to be a useful cyanomethyl source. The combination of copper and nickel catalysts resulted in a high reaction efficiency.

Recommanded Product: 91-02-1. The Name is Phenyl(pyridin-2-yl)methanone. Through research, I have a further understanding and discovery of 91-02-1.

Triazole-based ligands, tris (triazolyl)methanol (Htbtm), bis (triazolyl)-phenylmethanol (Hbtm), and phenyl (pyridin-2-yl)(triazolyl)methanol (Hpytm), with differences in ligand denticity (i.e., bidentate and tridentate) and type of N donors (i.e., triazole and pyridine) were functionalized onto a silica support to produce the corresponding SiO2-L (L = tbtm, btm, pytm). Subsequent reactions with Pd (CH3COO)(2) in CH2Cl2 yielded Pd/SiO2-L. ICP-MS reveals that Pd loadings are higher with increased N loadings, resulting in the following trend: Pd/SiO2-tbtm (0.83 mmol Pd g(-1)) > Pd/SiO2-btm (0.65 mmol Pd g(-1)) ~ Pd/SiO2-pytm (0.63 mmol Pd g(-1)). Meanwhile, TEM images of the used Pd/SiO2-L catalysts after the first catalytic cycle show that the mean size of Pd NPs is highest with Pd/SiO2-pytm (8.5 +/- 1.5 nm), followed by Pd/SiO2-tbtm (6.4 +/- 1.6 nm) and Pd/SiO2-btm (4.8 +/- 1.3 nm). Based on TONs, catalytic studies toward aerobic oxidation of benzyl alcohol to benzaldehyde at 60 degrees C in EtOH showed that Pd/SiO2-pytm possessed the most active surface Pd(0) atoms, most likely as a result of more labile properties of the pyridine-triazole ligand compared to tris- and bis (triazolyl) analogs. ICP-MS and TEM analysis of Pd/SiO2-btm indicate minimal Pd leaching and similar average Pd NPs sizes after 1(st) and 5(th) catalytic runs, respectively, confirming that SiO2-btm is an efficient Pd NPs stabilizer. The Pd/SiO2-btm catalyst was also active toward aerobic oxidation of various benzyl alcohol derivatives in EtOH and could be reused for at least 7 reaction cycles without a significant activity loss.

A new methodology for the highly efficient and atom-economic oxidation of alcohols and benzylic compounds to the corresponding aldehydes and ketones with environmental-friendly hydrogen peroxide using a magnetic MOF nanocatalyst has been developed. We demonstrated that the resulting magnetic nanocomposite CoFe2O4@SiO2@MIL-53(Fe) can show excellent catalytic performances in the highly selective oxidation at room temperature, based on a synergetic effect between iron sites and CoFe2O4@SiO2. The nanocatalyst offers simple operation for recovery and the recycling test showed that it could be reused for successive runs without significant degradation in catalytic activity.

The detrimental effect of electrolyte water contamination on the light-soaking lifetime of Dye-sensitized Solar Cells (DSCs) prepared with RuLL'(NCS)(2) dyes and N-additives like 4-tert-butylpyridine (TBP) is not well understood. A new explanation is presented based on investigation of the stability of the ruthenium(III) complexes Ru(bipy)(2)(NCS)(2)(+) (1(+)) and RuLL'(NCS)(2)(+) (L = 4,4′-dicarboxy-2,2′-bipyridine, L’ = 4,4′-nonyl-2,2′-bipyridine) (Z907(+)) in acetonitrile in the presence of water and pyridines covering a large variation in basicity. 1(+) reacts with small amounts of water in the acetonitrile containing a pyridine base (X) according to the overall reaction: 6Ru(bipy)(2)(NCS)(2)(+) + 4H(2)O + 8X -> 5Ru(bipy)(2)(NCS)(2) + Ru(bipy)(2)(NCS)(CN) + SO42- + 8XH(+). The reaction mechanism of 1(+) (and Z907(+)) is proposed to be initiated by an attack of OH- giving Ru(bipy)(2)(NCS)(NCS-OH). The stronger the base the faster the reaction. Extrapolating the life time of Z907(+) to a typical TBP concentration of 0.5 M in the DSC gives a degradation rate around 7 s(-1). Z907(+) bound to a layer of nano crystalline TiO2 surface reacted fast too, when inserted in an acetonitrile solution containing 4-tentbutylpyridine. In a wet electrolyte, containing more than 500 mM of water the light-soaking lifetime of a DSC prepared with Z907 is predicted to be about 10 days at out-door light soaking conditions, whereas trace amounts of water (< 25 mM) in a dry electrolyte is used up by consumption of only 10% of the Z907 in a typical DSC. Therefore, the DSC is expected to have a long light-soaking lifetime with a dry electrolyte. Application In Synthesis of Ethyl nicotinate.

This manuscript describes the design and synthesis of Ru catalysts that feature only a single stereogenic element, yet this minimal chirality resource is demonstrated to be competent for effecting high levels of stereoinduction in the asymmetric transfer hydrogenation over a broad range of ketone substrates, including those that are not accommodated by known catalyst systems. The single stereogenic center of the (1-pyridine-2-yl)methanamine) is the only point-chirality in the catalysts, which simplifies this catalyst system relative to existing literature protocols.

We herein report two complementary strategies employing organolithium chemistry for the synthesis of glyoxal derivatives. Micro-mixer technology allows for the generation of unstable organometallic intermediates and their instantaneous in-line quenching with esters as electrophiles. Selective mono-addition was observed via putative stabilized tetrahedral intermediates. Advantages offered by flow chemistry technologies facilitate direct and efficient access to masked 1,2-dicarbonyl compounds while mitigating undesired by-product formation. These two approaches enable the production of advanced and valuable synthetic building blocks for heterocyclic chemistry with throughputs of grams per minute.
