A new family of pyridyl-based NNN pincer ligands bearing a remote pendent OH group were developed. Considerable acceleration effects on the activity of Ru-catalyzed transfer hydrogenation of ketones were imparted by the pendent OH group, and importantly, introducing a CH2OH group to the 4′-position of the pyrazolyl moiety is an appropriate choice. The results present a general strategy for exploring bifunctional ligands to construct effective catalysts.

COA of Formula: C5H8N2. I found the field of Chemistry very interesting. Saw the article Syntheses, characterization and DFT studies of two new homo-dinuclear zinc(II) complexes based on pyrazole and 3,5-dimethylpyrazole ligands published in 2020.0, Reprint Addresses Ngoune, J (corresponding author), Univ Dschang, Dept Chem, Dschang, Cameroon.. The CAS is 67-51-6. Through research, I have a further understanding and discovery of 3,5-Dimethyl-1H-pyrazole.

Two new homo-dinuclear zinc(II) complexes, bis(mu-pyrazolato-) bis[(formato)(pyrazole)zinc(II)], [{Zn(OCHO)(pzH)}(2)(mu-N2H3C3)(2)] (1) and bis(mu-3,5-dimethylpyrazolato)bis[(formato)(-3,5-dimethylpyrazole) zinc(II)], [{Zn(dmpzH)(OCHO)}(2)(m-N2H7C5)(2)] (2), were synthesized through the reactions of zinc(II) formate dihydrate, Zn(OCHO)(2)center dot 2H(2)O with pyrazole (pzH = C3H4N2) and 3,5-dimethyl-pyrazole (dmpzH = C5H8N2), respectively, in toluene at room temperature. These dinuclear complexes have been characterized using different analytical techniques; elemental and thermogravimetric analyses, IR and H-1-NMR spectroscopies, single-crystal X-ray diffraction and DFT studies. Compound 1 crystallized in the P (1) over bar space group of the triclinic crystal system with unit cell parameters a = 8.205(3) angstrom, b = 8.864(5) angstrom, c = 14.486(7) angstrom, alpha = 104.929(14)degrees, beta = 91.214(11)degrees and gamma = 106.921(8)degrees. Compound 2 crystallized in the P2(1)/c space group of the monoclinic crystal system with cell parameters a = 8.400(3) angstrom, b = 11.020(4) angstrom, c = 14.930(5) angstrom, alpha = gamma = 90 degrees and beta = 106.3(10)degrees. Pseudo-tetrahedral coordination geometries were observed around the zinc(II) centers in both complexes, constructed by one oxygen atom from a formate anion and three nitrogen atoms from one pzH and two pyrazolato in 1 or one dmpzH and two 3,5-dimethylpyrazolato in 2. The bulk of these materials are consolidated by weak and strong N-H center dot center dot center dot O, C-H center dot center dot center dot O, C-N center dot center dot center dot O and C-H center dot center dot center dot pi, N-H center dot center dot center dot pi and C-O center dot center dot center dot O intra/intermolecular interactions resulting to zigzag networks containing empty voids. DFT studies on both compounds revealed their optimized structures, frontier molecular orbitals, theoretical IR frequencies and the global reactivity descriptors. [GRAPHICS]

Protein kinases control diversity of biochemical processes in human organism. Checkpoint 1 kinase (Chk1) is an important element of the checkpoint signalling pathways and is responsible for DNA damage repair. Hence, this kinase plays an essential role in cancer cells survival and has become an important target for anticancer agents. Our previous investigations showed that some arylsulphonyl indazole derivatives displayed anticancer effect in vitro. In the present study, in order to verify possibility of interactions of pyrazole and indazole derivatives with Chk1, we focused on the docking of selected tosyl derivatives of indazole and condensed pyrazole 1-7 to the Chk1 pocket, analysis of interactions involving optimized ligand-protein system using DFT formalism, and estimation of the interaction enthalpy of the ligand-protein complex by applying the PM7 method. The estimation of binding affinity seems to indicate that the indazole 5-substituted with 3,5-dimethylpyrazole 4 and condensed pyrazoloquinoline derivative 7 fit the best to the Chk1-binding pocket. The values of the energy of interaction, i.e. the enthalpy change (Delta H-int), were between – 85.06 and – 124.04 kcal mol(-1) for the optimized ligand-Chk1 complexes. The relaxation of the ligands within the complexes azole-protein as well as the distribution of hydrogen contacts between the ligands and kinase pocket amino acids was also analysed using molecular dynamics as a supporting method.

Based on the agrochemical structure of anthranilic diamides, fourteen novel N-substittitedphenyl-2-pyrazolylnicotinamides were conveniently synthesized with 2-chloro-3-cyanopyridine and 4-bromopyrazole or 3,5-dimethylpyrazole as starting materials, via an acyl transposing design strategy. Their structures were characterized by 1H NMR, 13C NMR and HRMS. The preliminary bioassay tests indicated that most of these compounds exhibited obvious insecticidal activity at the test concentration of 200 mg/L, among which N-(4-chloro-2-(ethylcarbamoyl)-6-methylphenyl)-2-(3,5-dimethyl-1H-pyrazol-1-yl)nicotinamide (II) possessed a 70% mortality rate against Mythimna separata Walker: some of the compounds displayed favorable fungicidal activities at 50 mg/L towards Physalospora piricola and Alternaria solani Sorauer, especially 2-(4-bromo-1H-pyrazol-1-yl)-N-(2-(cyclopropylcarbamoyl)-4-iodo-6-methylphenyl)nicotinamide (If) and 2-(4-bromo-1H-pyrazol-1-yl)-N-(4-chloro-2-(ethylcarbamoyl)-6-methylphenyl)nicotinamide (Ih) against Physalospora piricola, and 2-(4-bromo-1H-pyrazol-1-yl)-N-(4-chloro-2-(propylcarbamoyl)phenyl)nicotinamide (Id) against Alternaria solani Sorauer had growth inhibitory rates of 62.9%, 54.3% and 54.5%, respectively. These research results provide important reference for the further study of novel 2-pyrazolylnicotinamide derivatives.

Structural modulation of transition metal carboxylates has been studied by employing different auxiliary ligands in the reactions of metal acetates with substituted benzoic acids. A series of neutral transition metal benzoates [Cu(tbba)(2)(imH)(2)] (1), [Cu(tipba)(2)(2,4,6-collidine)(2)] (2), [Co(tbba)(2) (dmpH)(2)] (3), [Co(tipba)(2)(imH)(2)] (4), [M (tmba)(2)(pymeH)(2)] (M = Cu (5), Co (6) and Zn (7)), [Zn(tmba)(2)(pydmeH(2))] (8), [Cu-2(tmba)(2)(pydmeH(2))(2)] [(tmba)(2)(tmbaH)(2)] (9) and [Zn-2(dmp)(2) (tbba)(2)(dmpH)(2)] (10) have been isolated as products from the reaction between the respective metal acetates and substituted benzoic acids (acids used: 4-tert-butylbenzoic acid (tbbaH), 2,4,6-triisopropylbenzoic acid (tipbaH), 2,4,6-trimethylbenzoic acid (tmbaH)) and N-donor auxiliary ligands (imidazole (imH), 3,5-dimethylpyrazole (dmpH), 2,4,6-collidine, 2-pyridinemethanol (pymeH), and pyridine-2,6-dimethanol (pydmeH(2))). The new complexes have been characterized by both analytical and spectroscopic methods. The molecular structures of 1-10 have further been established by single crystal X-ray diffraction studies. The complexes 1-8 are mononuclear, while compounds 9 and 10 have been found to be dinuclear due to the role of benzoic acid in 9 and pyrazolate anion as bridging ligand in 10. The geometry around the metal ion is square-planar in 1 and 2, tetrahedral in 3, 4 and 10, octahedral in 5-7 and 9 and trigonal-bipyramidal in 8. Complexes with ligands that contain additional functional groups such as > NH and -OH are involved in hydrogen bonding interactions. These weak interactions lead to the formation of 1-D linear polymers or 2-D sheets.

We report the first asymmetric total synthesis and structural determination of calixanthomycin A. Taking advantage of a modular strategy, a concise approach was developed to assemble the hexacyclic skeleton with both enantiomers of the lactone A ring. Stereoselective glycosylation coupled the angular hexacyclic framework with a monosaccharide fragment to produce calixanthomycin A and its stereoisomers. This enable us to determine and assign the absolute configuration of C-25 (25S) and monosaccharide (derivative of L-glucose).

Using TiOⁱPr4 with a pyrazole ligand for one-pot LA polymerization improved catalytic activity compared with using TiOⁱPr4 only. At 60 degrees C, TiOⁱPr4 with ^furPz exhibited a higher catalytic activity (approximately 3-fold) than TiOⁱPr4. At room temperature, TiOⁱPr4 with ^BuPz exhibited a higher catalytic activity (approximately 17-fold) than TiOⁱPr4. High molecular mass PLA (MnGPC = 51 100, and D = 1.10) could be produced by using TiOⁱPr4 with ^furPz in melt polymerization ([TiOⁱPr4] : [^furPz] = 1000 : 1 : 1 at 100 degrees C, 240 min).

The construction of cyclobutanes has attracted much attention because of its unique four-membered ring skeleton. Herein, we report the highly enantioselective direct vinylogous Michael reaction of beta,gamma-unsaturated pyrazole amides and nitroolefin using a squaramide catalyst. Cyclobutane derivatives were obtained by subsequent cyclization in good yields (up to 85%) with excellent enantioselectivities (up to 99% ee). Importantly, the large-scale reaction experiment confirmed the reliability of the vinylogous reaction. Furthermore, the synthetic utility of the vinylogous adducts and cyclobutane derivatives has been realized.
