Click Chemistry Derived Pyridazines: Electron-Deficient Building Blocks with Defined Conformation and Packing Structure

A series of 3,6-bis(4-triazolyl)pyridazines equipped with terminal phenyl substituents with varying degree of fluorination were synthesized by using the facile copper-catalyzed azide-alkyne cycloaddition and their structures were thoroughly investigated in the gas phase, in solution, and in the solid state by employing DFT calculations, NMR spectroscopy, and single-crystal X-ray diffraction, respectively. On the molecular level, their structure is governed by the strong preference of the triazole-pyridazine linkages for the anti-conformation. The supramolecular organization of the molecules in the crystalline solid is controlled by -stacking, C-H as well as C-FH interactions. The latter can conveniently be tuned by the number and position of fluorine substituents in the terminal phenyl units, giving rise to either herringbone-like, 1D or 2D lamellar packing. Electrochemistry and optical spectroscopy of all compounds suggest that they might find use as electron-transporting/hole-blocking materials in organic electronics.

Convenient synthetic path to ethyl 1-aryl-5-formyl-1H-1,2,3-triazole-4-carboxylates and 1-aryl-1,5-dihydro-4H-[1,2,3]triazolo[4,5-d]pyridazin-4-ones

Static second hyperpolarizability of inverse sandwich compounds (M-1-C5H5-M-2) of alkali (M-1 = Li, Na, K) and alkaline earth metals (M-2 = Be, Mg, Ca)

In the investigated inverse sandwich complexes, charge transfer from alkali metal (M1) led to aromatically stabilized Cp ring, which prevented further charge transfer from the alkaline earth metal (M2). This electron push effect resulted in diffusion of electron density from the outermost ns” subshell of alkaline earth metal. The alkaline earth metal is weakly bound to the alkali metal-C5H5 complex. The vertical ionization energy of the chosen M1-Cp-M2 complexes was smaller than that of the corresponding alkaline earth metals. Large second hyperpolarizability (106-108 a. u.) was obtained for the studied molecules. The correction due to the basis set superposition error (BSSE) in the calculated second hyperpolarizability was found to be small for larger systems, while it was rather significant for small systems. The MP4SDQ and CCSD results were in fair agreement, which indicates the necessity of higher order electron correlation treatment in the accurate description of second hyperpolarizability. Calculated dynamic second hyperpolarizabilities at 1064 nm were found to increase considerably for most of the chosen metal complexes.

Luminescent thermometer based on Eu3+/Tb3+-organic-functionalized mesoporous silica

In this work we investigate a mesoporous silica (MS) decorated with dipyridyl-pyridazine (dppz) ligands and further grafted with a mixture of Eu3+/Tb3+ ions (28.45%:71.55%), which was investigated as a potential thermometer in the 10-360K temperature range. The MS material was prepared employing a hetero Diels-Alder reaction: 3,6-di(2-pyridyl)-1,2,4,5-tetrazine was reacted with the double bonds of vinyl-silica (vSilica) followed by an oxidation procedure. We explore using the dppz-vSilica material to obtain visible emitting luminescent materials and for obtaining a luminescent thermometer when grafted with Eu3+/Tb3+ ions. For the dppz-vSilica@Eu,Tb material absolute sensitivityS(a) of 0.011K(-1) (210K) and relative sensitivityS(r) of 1.32 %K-1 (260K) were calculated showing good sensing capability of the material. Upon temperature change from 10K to 360K the emission color of the material changed gradually from yellow to red.

Synthetic methodology towards allylictrans-cyclooctene-ethers enables modification of carbohydrates: bioorthogonal manipulation of thelacrepressor

The inverse electron-demand Diels-Alder (IEDDA) pyridazine elimination is one of the key bioorthogonal bond-breaking reactions. In this reactiontrans-cyclooctene (TCO) serves as a tetrazine responsive caging moiety for amines, carboxylic acids and alcohols. One issue to date has been the lack of synthetic methods towards TCO ethers from functionalized (aliphatic) alcohols, thereby restricting bioorthogonal utilization. Two novel reagents were developed to enable controlled formation ofcis-cyclooctene (CCO) ethers, followed by optimized photochemical isomerization to obtain TCO ethers. The method was exemplified by the controlled bioorthogonal activation of thelacoperon system inE. coliusing a TCO-ether-modified carbohydrate inducer.

Design, Synthesis and Anti-Tubercular Activity of Isoniazid Derivatives

The aim of this study was to develop novel isoniazid derivatives, which can be utilized as antitubercular agents. The compounds were synthesized by reaction between the hydrazine unit of isoniazid with an appropriate lipophilic moiety. The compounds obtained were characterized on the basis of their melting points, R-f value, Fourier Transform Infra Red (FTIR) Spectra, H-1-Nuclear Magnetic Resonance (H-1-NMR) Spectra, C-13- Nuclear Magnetic Resonance (C-13-NMR) Spectra, Elemetal Analysis, and the Mass spectra. The novel compounds were assessed for their anti-tubercular activity by reported method against four strains of the Mycobacterium. The minimum inhibitory concentration of the active compounds was also determined. The anti-tubercular activity data revealed that most of the compounds have higher MIC values as compared to the standard drug isoniazid. Two compounds, namely 3b and 3c, exhibited very good anti-tubercular activity against all four strains of the Mycobacterium, which was comparable to the standard drug isoniazid. It has been concluded that the incorporation of a lipophilic chain at the position-2 of the pyridazine ring along with a halogen group, preferably a fluorine atom, at the p-position of the phenyl ring in this series of compounds increase the anti-tubercular activity of the compounds. However, this assumption cannot be generalized because in the present study the anti-tubercular activity was assessed against four strains of Mycobacterium. Accordingly, further studies are recommended to assess the anti-tubercular activity of these two compounds, 3b and 3c, against other strains of the Mycobacterium.

I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 102-08-9 help many people in the next few years. COA of Formula: C13H12N2S.
