Cho, Il Young published the artcileNickelocene as an Air- and Moisture-Tolerant Precatalyst in the Regioselective Synthesis of Multisubstituted Pyridines, Computed Properties of 100-70-9, the main research area is pyridine derivative regioselective preparation; diyne nitrile cycloaddition nickelocene catalyst.

Herein, operationally simple nickel(0) catalysis to access substituted pyridines I [R = Me, Ph, 2-furyl, etc.; R1 = Me, Ph, trimethylsilyl, etc.; R2 = H, Me, Ph, etc.; Z = CH2, O, C(CO2Et)2, N-Ts] from various nitriles and 1,6-diynes without the aid of air-free techniques was reported. The Ni-Xantphos-based catalytic manifold was tolerant to air, moisture and heat while promoting the [2 + 2 + 2] cycloaddition reactions with high reaction yields and broad substrate scope. In addition, the steric effect but also the frontier MO interactions could played a critical role in determining the regiochem. outcome of nickel-catalyzed [2 + 2 + 2] cycloaddition for the synthesis of compounds I.

Kumar, Girijesh published the artcileSynthesis and photophysical properties of pyridyl conjugated triazole appended naphthalenediimide derivatives, Computed Properties of 100-70-9, the main research area is bis dipyridinyltriazolyl phenanthroline tetraone preparation reduction potential fluorescence.

A series of three substituted triazole appended naphthalenediimide (NDI)-derivatives, 2,7-bis(3,5-di(pyridin-X-yl)-4H-1,2,4-triazol-4-yl)benzo[lmn][3,8]phenanthroline-1,3,6,8(2H,7H)-tetraones (where X = 2, NDI-PyTz-1; 3, NDI-PyTz-2; and 4, NDI-PyTz-3), were designed, synthesized and well characterized using various anal. and spectroscopic techniques. All the three NDI-PyTz derivatives exhibited decent electronic properties as suggested by DFT, cyclic voltammetry and fluorescence studies. In particular, NDI-PyTz-1 demonstrated the generation of a stable anion radical [NDI-PyTz-1].-.

Wilkovitsch, Martin published the artcileA Cleavable C2-Symmetric trans-Cyclooctene Enables Fast and Complete Bioorthogonal Disassembly of Molecular Probes, SDS of cas: 100-70-9, the main research area is bioorthogonal disassembly mol fluorescent probe trans cyclooctene cell imaging.

Bioorthogonal chem. is bridging the divide between static chem. connectivity and the dynamic physiol. regulation of mol. state, enabling in situ transformations that drive multiple technologies. In spite of maturing mechanistic understanding and new bioorthogonal bond-cleavage reactions, the broader goal of mol. ON/OFF control has been limited by the inability of existing systems to achieve both fast (i.e., seconds to minutes, not hours) and complete (i.e., >99%) cleavage. To attain the stringent performance characteristics needed for high fidelity mol. inactivation, we have designed and synthesized a new C2-sym. trans-cyclooctene linker (C2TCO) that exhibits excellent biol. stability and can be rapidly and completely cleaved with functionalized alkyl-, aryl-, and H-tetrazines, irresp. of click orientation. By incorporation of C2TCO into fluorescent mol. probes, we demonstrate highly efficient extracellular and intracellular bioorthogonal disassembly via omnidirectional tetrazine-triggered cleavage.

Huang, Zhuo-Bin published the artcileSelectively Oxidative Thiolysis of Nitriles into Primary Thioamides and Insecticidal Application, Name: Picolinonitrile, the main research area is aryl carbothioamide preparation green chem agrochem toxicity.

Primary thioamides were useful building blocks for drug and insecticide development, therefore an environmentally benign synthesis of primary thioamides was desired. An oxidative thiolysis for the selective transformation of nitriles into primary thioamides using elemental sulfur or thiuram in the presence of K2S2O8 in DMF/H2O was discussed. This practical method enables access to a wide range of synthetically and pharmaceutically useful primary thioamides. Advantages of this reaction include transition-metal-free and base-free reaction conditions, use of an environmentally benign solvent (DMF/H2O) system, the use of non-toxic elemental sulfur or thiuram as the sulfur sources, and good functional groups tolerances with excellent selectivity. Furthermore, the insecticide Fipronil was also converted to the corresponding thioamide and maintains excellent bioactivity against P. xylostella. The LC50 value of Fipronil thioamide was 1.25 mg/L.

Sharma, Swagat published the artcileDiscovery, synthesis and characterization of a series of (1-alkyl-3-methyl-1H-pyrazol-5-yl)-2-(5-aryl-2H-tetrazol-2-yl)acetamides as novel GIRK1/2 potassium channel activators, Category: nitriles-buliding-blocks, the main research area is pyrazolyl arylazolyl acetamide preparation GIRK channel activator SAR; Activator; G protein-regulated inwardly-rectifying potassium channel; GIRK; Tetrazole.

The study described the discovery and characterization of a series of 5-aryl-2H-tetrazol-3-yl acetamides as G protein-gated inwardly-rectifying potassium (GIRK) channels activators. Working from an initial hit discovered during a high-throughput screening campaign, a tetrazole scaffold was identified that shifts away from the previously reported urea-based scaffolds while remaining effective GIRK1/2 channel activators. In addition, the compounds were evaluated in Tier 1 DMPK assays and identified a (3-methyl-1H-pyrazol-1-yl)tetrahydrothiophene-1,1-dioxide head group that imparts interesting and unexpected microsomal stability compared to previously-reported pyrazole head groups.

Tlusty, M. published the artcileRegioselective formation of the quinazoline moiety on the upper rim of calix[4]arene as a route to inherently chiral systems, Synthetic Route of 100-70-9, the main research area is calixarene quinazoline conformation crystal structure pi interaction inclusion compound.

The meta- and para-substituted aminocalix[4]arenes immobilized in the cone conformation were acylated to yield the corresponding acyl amides. Subsequent cyclization with aryl or alkyl cyanides afforded the expected quinazolines only in the case of the para-substituted series, while only complex reaction mixtures were obtained for the meta-substituted analogs. This finding was used as a strategy for the preparation of novel inherently chiral calixarenes with strong fluorescence. The structure of the products was proved by the combination of NMR and single crystal X-ray analyses. The dynamic NMR study of quinazoline derivatives revealed the existence of two different atropisomers in solution at lower temperatures As evidenced by resolution with a chiral HPLC column and by the fluorescence titration experiments, novel quinazolines represent inherently chiral macrocycles of high potential for the design of chiral calixarene-based receptors.
