Application of [4+2] Cycloaddition Reaction of Tetrazine with Cyclooctyne in the Construction of Pyridazine Structure with Axial Chirality

The application of [4+2] cycloaddition reaction of tetrazine with cyclooctyne in the construction of pyridazine structure with axial chirality was studied. The inverse electronic demand Diels-Alder reaction of tetrazine bearing bulky groups with macrocyclic tension’s cyclooctyne could take place under catalyst-free conditions in dichloromethane. The reaction underwent a six-membered bridged transition state, gently release a molecule of nitrogen to get axial chiral pyridazine structure. The transformation of the reaction can be determined by the change of color. The reaction could get potential axial chiral pyridazine structure with high yiled (95%) under mild conditions.

Synthesis and structure-activity relationship study of novel 3-heteroarylcoumarins based on pyridazine scaffold as selective MAO-B inhibitors

Compounds of hybrid structure pyridazine-coumarin were discovered as potent, selective and reversible inhibitors of monoamine oxidase B (MAO-B). These compounds were synthesized in good yield following a multistep approach based on Knoevenagel reaction and using as key intermediate pyridazinone 16, which was obtained from maleic anhydride and furan. Compounds 9b and 9d are the most active compounds of these series, with IC50 values in the sub-micromolar range, and lack of cytotoxic effects. Theoretical calculation of ADME properties also suggested a good pharmacokinetic profile for both compounds. Docking simulations provided insights into enzyme inhibitor interactions and allowed us to rationalize the observed structure-activity relationships (SARs). (C) 2017 Elsevier Masson SAS.

Pyridazine-Containing Diazatwistanthracene and Tetraazatwisttetracene: Synthesis, Crystal Structures and Third Order Non-linear Optical Properties

In this paper, two pyridazine-heterocycles-containing azaacenes 9,12-diphenylphenanthro[4,5-fgh]phthalazine (DPPA) and 2,9-di-tert-butyl-4,7,11,14-tetraphenylpyridazino[4′,5′:9,10] phenanthro[4,5-fgh]phthalazine (TPPA) have been synthesized and fully characterized. The single crystal analysis of TPPA showed that TPPA molecule exhibits a twisted structure with the dihedral angel of 27 degrees between pyrene and pyridazine unit, which suppresses the pi-pi stackings in the solid state. The two-photon absorption properties of DPPA and TPPA were investigated, respectively, by using the femtosecond Z-scan technique. The results showed that both DPPA and TPPA showed moderate two-photon absorption cross-section values, and the larger one was found to be 454 GM with TPPA. Obviously, the introduction of pyridazine ring into the skeleton of acenes forming a A-D-A structure could lead to a much larger two-photon absorption coefficient and two-photon absorption cross section.

Imidazo[1,2-b]pyridazine as Building Blocks for Host Materials for High-Performance Red-Phosphorescent Organic Light-Emitting Devices

A novel electron-transporting unit, imidazo [1,2-b]pyridazine (IP), was first reported for developing host materials. The IP moiety possesses excellent electron-transporting ability and great thermal stability. Using carbazole as p-type units and IP as n-type units, several bipolar host materials, namely, IP6Cz, IP68Cz, IP36Cz, and IP368Cz, were developed through altering the substitution site of the IP core. Among these four materials, 6-site-substituted IP6Cz and 6,8-site-substituted IP68Cz exhibit the best electroluminescence (EL) performance. IP6Cz- and IP68Cz-based red phosphorescent organic light-emitting diodes using Ir(pq)(2)acac as the emitter exhibit extremely high EL efficiency with the maximum external quantum efficiency (eta(ext,max)) of 26.9 and 25.2% and an insignificant efficiency roll-off. Moreover, IP6Cz- and IP68Cz-based deep-red devices doped by Ir(piq)(2)acac also show satisfactory EL performance with a eta(ext,max) of 20.5 and 19.9%, respectively. The influence of different substitution sites of the IP core on the photophysical and electrochemical properties was systematically investigated. This study demonstrates that IP could be a first-rate electron-transporting unit for bipolar materials for red-emitting devices.

p-Cymene Complexes of Ruthenium(II) as Antitumor Agents

In this work, the cytotoxic behavior of six ruthenium(II) complexes of stoichiometry [(eta(6)-p-cymene)RuCl2L] (I-VI), L = 4-cyanopyridine (I), 2-aminophenol (II), 4-aminophenol (III), pyridazine (IV), and [(eta(6)-p-cymene)RuClL2]PF6; L = cyanopyridine (V), L = 2-aminophenol(VI) towards three cell lines was studied. Two of them, HeLa and MCF-7, are human carcinogenic cells from cervical carcinoma and human breast cancer, respectively. A comparison with healthy cells was carried out with BGM cells which are monkey epithelial cells of renal origin. The behavior of complex II exhibits selectivity towards healthy cells, which is a promising feature for use in cancer treatment since it might reduce the side effects of most current therapies.

Synthesis of pertrifluoromethyl pyridazine derivatives via a tandem reaction of aryldiazonium salts with hexafluoroacetylacetone

A new strategy for the construction of pertrifluoromethyl pyridazine derivatives is presented. The tandem reaction starts from the condensation of arenediazonium salts with hexafluoroacetylacetone leading to the formation of pertrifluoromethyl pyridazinols, which readily undergo electrophilic substitution reactions with phenols to afford benzo[5,6]chromeno[3,4-c]pyridazine products in the presence of concd H2SO4.

Generation of Annelated Dicarbenes and Their Alkali-Metal Chelate Complexes in Solution: Equilibrium between Hetero- and Homoleptic NHC Lithium Complexes

Attempts to generate the free bis(N-heterocyclic carbene) vegi(R) (R = nPr, tBu; vegi(R) = 2,L7-dihydro-2,7-dialkyldiimidazo[1,5-b:5′,1′-f]pyridazine-1,8-diylidene) from its imidazolium salts 1 with alkali-metal bases resulted exclusively in the formation of the respective lithium, sodium, and potassium complexes 2-4 due to the strongly chelating properties of the dicarbene. DFT calculations reveal pronounced dispersion interactions in the case of N-tertbutyl substituents as the reason for the formation of the homoleptic lithium species 2b-H in solution. The dynamic behavior of the lithium complexes in equilibrium was studied by NMR techniques. Attempts to liberate the free carbenes by addition of the respective crown ethers failed for the lithium and sodium complexes. Deprotonation of the imidazolium salts 1a,b with the strong metal-free phosphazene base P4-tBu ({(Me2N)(3)PN}(3)PNtBu) generated successfully the free dicarbenes vegi(R) (5) and monocarbene 6b in solution.
