Fe3O4@silica sulfuric acid nanoparticles: An efficient reusable nanomagnetic catalyst as potent solid acid for one-pot solvent-free synthesis of indazolo[2,1-b]phthalazine-triones and pyrazolo[1,2-b]phthalazine-diones

Regarding the green chemistry’s goals, silica-coated magnetite nanoparticles (MNPs) open up new avenue to introduce an amazing and efficient system for facilitating catalyst recovery in different organic reactions. Therefore, in this paper the preparation of sulfuric acid functionalized silica-coated magnetite nanoparticles with core-shell structure (Fe3O4@silica sulfuric acid) are presented by using Fe3O4 spheres as the core and silica sulfuric acid nanoparticles as the shell. The catalyst was characterized by infrared spectroscopy (FT-IR), scanning electron microscope (SEM), transmission electron microscopy (TEM), X-ray diffraction (XRD) spectroscopy, and vibrating sample magnetometer (VSM). Ability of this nano-magnetic solid acid catalyst in the one-pot three-components condensation reaction of phthalhydrazide, aromatic aldehydes and cyclic or acyclic 1,3-diketones are also described. Utilization of easy reaction conditions, catalyst with high catalytic activity and good reusability, and simple magnetically work-up, makes this methodology as an interesting option for the economic synthesis of indazolo[2,1-b]phthalazine-triones and pyrazolo[1,2-b]phthalazine-diones.

The geometry, electronic structure, natural bond orbitals (NBO) and molecular electrostatic potential (MEP) surface analysis were carried out for some bis 1H-Indazolo [1,2-b]phthalazine-triones using HF/3-21G computational method. The theoretical studies revealed the existense of intramoleculare hydrogen bonds and high HOMO-LUMO energy gap for the products structures. Some advantages of this protocol are high yields, short reaction times, simple purification, and environmentally mild reaction conditions. Furthermore, the catalyst was reused at least six times without substantial loss of catalytic activity. (C) 2019 Elsevier B.V. All rights reserved.

Synthesis, structural characterization, and molecular docking study of new phthalhydrazide-coumarin hybrids

A series of new phthalhydrazide-coumarin hybrids was obtained in the reaction of phthalhydrazide with corresponding bromopropoxycoumarin derivatives. These reactions were performed in the presence of Cs2CO3, in acetonitrile as solvent, and under reflux for 5 h. Obtained hybrids contain one or two coumarin scaffolds bonded to phthalhydrazide nitrogen via propoxy linker. Ten new phthalhydrazide-coumarin hybrids were obtained in moderate to good yields, and characterized with melting point, elemental analysis, IR and NMR spectroscopy, and LC-MS spectrometry. Additionally, the structures of these compounds were elucidated based on experimental and theoretical data (IR, H-1 NMR, and C-13 NMR). Excellent agreement between experimental and simulated spectra was achieved. The prediction of the potential biological activity of synthesized compounds was done using the online program PASS (Prediction of Activity Spectra for Substances). Based on the obtained results, the serotonin 2A receptor (5-HT2AR) was selected for molecular docking study. Molecular docking was also performed with commercially available drug Risperidone, and obtained results were compared with potential bioactive conformations of obtained phthalhydrazide-coumarin hybrids.

Cu@Fe3O4 MNPs as novel nanomagnetic reagents were prepared to investigate their catalytic behavior in the preparation of tetrahydrobenzimidazo[2,1-b]quinazolin-1(2H)-ones, as important biologically active compounds. Then, characterization of the synthesized nanoparticles was performed using different methods including Fourier transform infrared spectroscopy (FT-IR), X-ray diffraction (XRD) analysis, thermogravimetric analysis (TGA), vibrating sample magnetometer (VSM), energy dispersive X-ray (EDX), and scanning electron microscopy (SEM). All reactions were performed with small amounts of the Cu@Fe3O4 MNPs under solvent-free conditions. After completion of the reaction, because of the magnetic nature of the nanocatalyst, they could be simply separated with an external magnet and easily reused with no considerable decrease in the catalytic behavior even after seven runs.

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.
