Effective and Transition-Metal-Free Construction of Disubstituted, Trisubstituted 1,2,3-NH-Triazoles and Triazolo Pyridazine via Intermolecular 1,3-Dipolar Cycloaddition Reaction

An interesting approach for synthesis of disubstituted-1,2,3-(NH) triazoles from easily available raw materials and reagents like substituted acetophenones, iodine, DMSO and NaN3 via intermolecular 1,3-dipolar cycloaddition reaction. Trisubstituted triazoles and its corresponding triazolo pyridazine could be made easily using this method. These are key intermediates for poly benzodithiophene triazole (PBnDT-TAZ) for solar cells and 1-benzyl-1H-4,5-dibenzoyl-1,2,3-triazole (BDBT) for corrosion inhibition.

A facile approach toward 1,2-diazabenzo-[ghi]perylene derivatives: structures and electronic properties

A new class of pyridazine fused aromatics, 1,2-diazabenzo-[ghi]perylenes, is conveniently synthesized from 2,7-dihydroxynaphthalene via intermolecular oxidative coupling followed by a condensation reaction. These new compounds are fully characterized via X-ray crystallographic analysis, optical spectroscopy and electrochemistry, in addition to DFT calculations. They show a twisted structure and unique P-/P- and M-/M-enantiomer pairs are observed in their single crystals. They exhibit intramolecular charge transfer character and emit at a longer wavelength with a larger Stokes shift compared with their all-carbon analog.

Lewis Acid Catalyzed Annulation of Cyclopropane Carbaldehydes and Aryl Hydrazines: Construction of Tetrahydropyridazines and Application Toward a One-Pot Synthesis of Hexahydropyrrolo[1,2-b]pyridazines

In this report, a facile synthesis of tetrahydropyridazines via a Lewis acid catalyzed annulation reaction of cyclopropane carbaldehydes and aryl hydrazines has been demonstrated. Moreover, the generated tetrahydropyridazine further participated in a cycloaddition reaction with donor-acceptor cyclopropanes to furnish hexahydropyrrolo[1,2-b]pyridazines. We also performed these two steps in one pot in a consecutive manner. In addition, a monodecarboxylation reaction of hexahydropyrrolo[1,2-b]pyridazine was achieved with a good yield.

Metal-Free Direct C-H beta-Carbonyl Alkylation of Heteroarenes with Cyclopropanols Mediated by K2S2O8

Direct C-H beta-carbonyl alkylation of heteroarenes under metal-, acid- and photo-catalyst free conditions has been achieved. A wide scope of substrates, such as various substituted quinolines and isoquinolines, pyridines, pyridazine, benzo[d]thiazole and phenanthroline, underwent the beta-carbonyl alkylation efficiently via K2S2O8-mediated ring-opening of cyclopropanols. The corresponding beta-heteroarylated ketones were obtained in moderate to excellent yields and gram-scale experiments further demonstrated the practicality of this synthetic protocol. The readily available reagents, mild and environmentally benign conditions make the method extremely attractive. The reaction mechanism is also proposed.

Acid-Induced Multicolor Fluorescence of Pyridazine Derivative

Smart luminescent materials that are responsive to external stimuli have received considerable attention. Here, we report a new D-A type 1,2-pyridiazine derivative (3,4,5,6tetrakis(4-methoxyphenyl)pyridazine (TPP)) exhibiting turn on fluorescence upon acid exposure both in solution and in the solid state. The protonation of the 1,2-pyridiazine ring caused a variation in the emission colors of the acidification species from blue (406 nm) to orange-red (630 nm) with a huge Ailem (224 nm). As a result, a synthetic rainbow of emission in solution could be achieved from one single molecule, and white photoluminescence was readily tuned by controlled protonation. A trifluoroacetic acid (TFA)-sensor film made from TPP was demonstrated as a TFA-sensitive surface with high sensitivity and reversibility. On the basis of these findings, we constructed a solid-state TPP film with a photoacid generator and demonstrated data encryption and decryption via a cascade protonation reaction that was well controlled by UV light.

Synthesis, chemical behavior, structure elucidation and iNOS inhibitory activity of 1-substituted3-methylsulfany1-5,6,7,8-tetrahydro-1H-[1,2,4]-triazolo[1,2-a]pyridazines

Novel slim and shapely spa-rich nitrogen containing heterocyclic ring systems are sought-after platforms for the expansion of molecular diversity in lead discovery.The present work describes the synthesis and characterization of a series of derivatives of hitherto unknown 3-methylsulfany1-5,6,7,8-tetrahydro-1H-[1,2,4]triazolo[1,2-a]pyridazines 2. This approach was guided by a computational study, aiming at an optimization of previously reported [1,2,4]triazolo[1,2-a]pyridazine-1-thiones 1 known to inhibit the inducible nitric oxide synthase (iNOS). The title compounds are accessible by methylation of compounds 1 under mild conditions. The products were biologically evaluated by the same cell-based assay as applied for previous products of type 1 using RINm5F cells, which were stimulated to produce NO on the influence of proinflammatory cytokines IL-1 beta and IFN-y. Compounds 2 did not display the anticipated improved iNOS inhibitory activity in the selected assay but contribute to SAR in the field. In addition, an unprecedented formation of side-products 3 via oxidation has been investigated. The novel scaffolds represent attractive starting points for the construction of diverse molecules which differ considerably from known compounds based on flat and lipophilic aromatic scaffolds.

Achieving High Levels of NMR-Hyperpolarization in Aqueous Media With Minimal Catalyst Contamination Using SABRE

Signal amplification by reversible exchange (SABRE) is shown to allow access to strongly enhanced H-1 NMR signals in a range of substrates in aqueous media. To achieve this outcome, phase-transfer catalysis is exploited, which leads to less than 1.5 V 10(-6) mol dm(-3) of the iridium catalyst in the aqueous phase. These observations reflect a compelling route to produce a saline-based hyperpolarized bolus in just a few seconds for subsequent in vivo MRI monitoring. The new process has been called catalyst separated hyperpolarization through signal amplification by reversible exchange or CASH-SABRE. We illustrate this method for the substrates pyrazine, 5-methylpyrimidine, 4,6-d(2)-methyl nicotinate, 4,6-d(2)-nicotinamide and pyridazine achieving 1H signal gains of approximately 790-, 340-, 3000-, 260- and 380-fold per proton at 9.4 T at the time point at which phase separation is complete.

Electric Literature of 73963-42-5, Consequently, the presence of a catalyst will permit a system to reach equilibrium more quickly, but it has no effect on the position of the equilibrium as reflected in the value of its equilibrium constant.I hope my blog about 73963-42-5 is helpful to your research.
