Synthesis of new (trifluoromethyl)-1H-benzo[e][1,2,4]triazolo[1,2-a] [1,2,4]triazine-1,3(2H)-diones and (trifluoromethyl)benzo[5,6][1,2,4] triazino [1,2-b]phthalazine-8,13-diones

In this paper we investigated reactions of urazole and phthalazine with N-(aryl)-2,2,2-trifluoroacetimidoyl chloride derivatives. Results showed that when imidoyl chloride derivative has a fluorine atom at ortho position (3a-c), in two steps under a S(N)i mechanism and then SNAr reaction mechanism produce ay1-5-(trifluoromethyl)-1H-benzo [el [1,2,4]triazolo[1,2-a] [1,2,4]triazine-1,3(2H)-diones (4a-c) and 6-(trifluoromethyl)benzo[5,6][1,2,4]triazino[1,2-b]phthalazine-8,13-diones (4i,4j) in good to excellent yields. In the other imidoyl derivatives (3d-h and 3i,3j) under these conditions cyclization reaction does not occur and therefore produce 1-aryl-2,2,2-trifluorornethyl)-4-phenyl-1,2,4-triazolidine-3,5-diones (4d-h) and 2-(2,2,2-trifluoro-1-(arylimino)ethyl)-2,3-dihydrophthalazine-1,4-diones(4k,41) (non-cyclic products) in good to excellent yields.

Crystallographic Study on the Structure of 5,6,7,8-Tetrahydro-1,4-di (2 ‘-pyridyl) Phthalazine

The solid-state structure of 5,6,7,8-tetrahydro-1,4-di(2’-pyridyl)phthalazine (6-dppn) was characterized by X-ray diffraction and a crystallographic study was then conducted. It was found that 6-dppn exists in the trans/trans conformation. This ligand crystallizes in P2(1)/c(14) space group with unit cell parameters of a = 9.698(2) angstrom, b = 9.999(4) angstrom, c = 10.7268(3) angstrom, beta = 92.890(6)degrees, Z = 8 and V = 2958.2(14) angstrom(3). The non-covalent interactions involved in the structure of 6-dppn were investigated and presented in terms of supramolecular chemistry and crystal engineering.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 83-38-5. Name: 2,6-Dichlorobenzaldehyde.

Synthesis and Antitumor Activity of Novel 1,3-Disubstituted Pyridazinone Derivatives

In order to find more efficient and low toxicity antitumor drugs, a series of novel 1,3-disubstituted pyridazinone derivatives were synthesized and evaluated for their antiproliferative activities against four human cancer cell lines (MCF-7, PC-3, SW-620 and HGC-27) in vitro. The results showed that most compounds had good antiproliferative activities, especially 2-(4-(4-bromophenyl)-1-oxo-tolylazine-2(1H)-yl)-N-(2-fluorophenyl)acetamide (5g) exhibited better antiproliferative activities with IC50 value of 6.01 mu mol/L. In a nutshell, this work provided clues to discover antitumor agent based on the quinazoline scaffold.

Organoacid-Decorated NiFe2O4 Nanoparticles: An Efficient Catalyst for Green Synthesis of 2H-Indazolo[2, 1-b]phthalazine-Triones and Pyrimido[1,2-a]benzimidazoles

Organo-Sulfonic acid tags anchored on magnetic titana coated NiFe2O4 nanoparticles (nano-NiFe2O4@TiO2-SiO2-Pr-DEA-OSO3H) was prepared and characterized by various analysis methods including Fourier transform infrared (FT-IR) spectroscopy, field emission scanning electron microscopy (FE-SEM), energy dispersive X-ray spectroscopy (EDS), vibrating sample magnetometer (VSM), X-ray diffraction (XRD) and thermo gravimetric analysis (TGA). These modified nanoparticles were used as efficient and recoverable hybrid nanocatalyst in multicomponent synthesis of some phthalazine-trione and benzo[4,5]imidazo[1,2-a]pyrimidine derivatives under green conditions. High yields within shorter reaction times, simple purification, and environmentally mild reaction conditions are some advantages of this protocol.

Introducing new and effective catalysts for the synthesis of pyridazino[1,2-a]indazole, indazolo[2,1-b]phthalazine and pyrazolo[1,2-b]phthalazine derivatives

In this study, a new and effective catalyst for the synthesis of pyridazino[1,2-a]indazole, indazolo[2,1-b]phthalazine and pyrazolo[1,2-b]phthalazine derivatives was introduced. Triethanolammonium acetate ([TEAH][OAc]) accelerates the reaction in a one-pot and four-component condensation of aldehydes, hydrazine hydrate, succinic/phthalic anhydride, and 1,3-dicarbonyl compounds. The yield of the products is high, and the reaction conditions are mild and solvent-free. Furthermore, the model reaction was conducted in the presence of triethanolammonium sulphate ([TEAH][HSO4] and triethanolammonium formate ([TEAH][HCOO]) under various conditions. In addition, the catalyst is recyclable, therefore, it can be reused several times. The structure of the obtained products was confirmed by comparing the M.P., IR, and H-1 NMR. Advantages of this technique are as following: Synthesis of novel, green, and one-pot and four-component condensation (4CC) under solvent-free conditions at room temperature. The catalytic reaction is performed under mild and environmentally friendly conditions in short reaction times and excellent yields. The catalyst is easily recycled and exhibits good chemical and structural stability. (C) 2020 The Author(s). Published by Elsevier B.V.

Four new complex compounds of bis(phthalazine-1-hydrazone)-2,6-diacetylpyridine (Hz(2)DAP) ligand with Ni-II, Co-III, Cu-II and Zn-II metal centres were synthesised and characterised by single-crystal X-ray diffraction and IR spectral data. The antimicrobial activity of Hz(2)DAP and the obtained complexes [Co(Hz(2)DAP-H)Cl-2]center dot MeOH, [Ni(Hz(2)DAP-H)]Cl center dot MeOH, [Cu(Hz(2)DAP-H)Cl] and [Zn(Hz(2)DAP-2H)]center dot H2O were tested in vitro against selected Gram(-) and Gram(+) bacterial strains and fungi. The antimicrobial activity of the ligand is negligible, while its complexes with Ni-II, Co-III and Cu-II show considerable activity against Escherichia coli, Staphylococcus aureus and Micrococcus lysodeikticus. On the contrary, [Zn(Hz(2)DAP-2H)]center dot H2O promotes the growth of Candida albicans, while its antibacterial activity is negligible.

Phthalazine-triones: Calix[4]arene-assisted synthesis using green solvents and their anticancer activities against human cancer cells

Fourteen phthalazine-triones bearing different substituents at C-4 position were synthesized through multicomponent reactions (MCR) by using phthalhydrazide, dimedone and diferent aldehydes as starting materials, p-sulfonic acid calix[4]arene as catalyst and ethyl lactate as solvent under microwave irradiation. Compounds 7-16 were obtained in excellent to moderate yields (94-51%) in only 10 min of reaction using this methodology. The antiproliferative activity against cancer cells was disclosed, for the first time, for synthesized compounds. The capacity of all compounds to inhibit cancer cells growth was dependent on the histological origin of cells. Compound 20 was active against more than one strain. (C) 2016 The Authors.

A simple and cost-efficient technique to generate hyperpolarized long-lived N-15-N-15 nuclear spin order in a diazine by signal amplification by reversible exchange

Signal Amplification by Reversible Exchange (SABRE) is an inexpensive and simple hyperpolarization technique that is capable of boosting nuclear magnetic resonance sensitivity by several orders of magnitude. It utilizes the reversible binding of para-hydrogen, as hydride ligands, and a substrate of interest to a metal catalyst to allow for polarization transfer from para-hydrogen into substrate nuclear spins. While the resulting nuclear spin populations can be dramatically larger than those normally created, their lifetime sets a strict upper limit on the experimental timeframe. Consequently, short nuclear spin lifetimes are a challenge for hyperpolarized metabolic imaging. In this report, we demonstrate how both hyperpolarization and long nuclear spin lifetime can be simultaneously achieved in nitrogen-15 containing derivatives of pyridazine and phthalazine by SABRE. These substrates were chosen to reflect two distinct classes of N-15(2)-coupled species that differ according to their chemical symmetry and thereby achieve different nuclear spin lifetimes. The pyridazine derivative proves to exhibit a signal lifetime of similar to 2.5 min and can be produced with a signal enhancement of similar to 2700. In contrast, while the phthalazine derivative yields a superior 15 000-fold N-15 signal enhancement at 11.7 T, it has a much shorter signal lifetime.
