Massi, Massimiliano,Ogden, Mark I.,Radomirovic, Tomoko,Jones, Franca
, p. 4205 - 4207 (2010)
Tetrazoles are a class of organic compound often used as carboxylic acid analogues. This analogous behaviour is shown to extend to crystallization modification, that is, tetrazoles are also able to influence crystal growth and morphology although in a dif

The designed molecular structures have been subjected to computational analysis for calculating their physicochemical properties and drug likeness. The calculated data indicate that most of the compound possess the bioactivity score in the active zone. Synthetic approach to the target compounds is straightforward and easy to handle. Structures of the new compounds are supported by FT-IR, 1H, and 13C NMR, and mass spectra. Antimicrobial tests of the products against pathogens (S. aureus, S. epidermidis, E. coli, and P. mirabilis) indicate the products as active or highly active. Their cyto-toxicity is determined to be 92–98% at concentration of 3.125 μmol/L. The molecular docking analysis carried out for the target compounds against the receptor Glc-N-6P exhibits low binding energy and various binding sites of those.
Biosynthesis of Pd/MnO2 nanocomposite using Solanum melongena plant extract and its application for the one-pot synthesis of 5-substituted 1H-tetrazoles from aryl halides
Nasrollahzadeh, Mahmoud,Ghorbannezhad, Fatemeh,Sajadi, S. Mohammad
, (2018/12/14)
In this work, for the first time, Solanum melongena plant extract was used for the green synthesis of Pd/MnO2 nanocomposite via reduction osf Pd(II) ions to Pd(0) and their immobilization on the surface of manganese dioxide (MnO2) nanoparticles (NPs) as an effective support. The synthesized nanocomposite were characterized by various analytical techniques such as Fourier transform infrared (FT-IR), X-ray diffraction (XRD), transmission electron microscopy (TEM), field emission scanning electron microscopy (FESEM), energy dispersive X-ray spectroscopy (EDS) and UV–Vis spectroscopy. The catalytic activity of Pd/MnO2 nanocomposite was used as a heterogeneous catalyst for the one-pot synthesis of 5-substituted 1H-tetrazoles from aryl halides containing various electron-donating or electron-withdrawing groups in the presence of K4[Fe (CN)6] as non-toxic cyanide source and sodium azide. The products were obtained in good yields via a simple methodology and easy work-up. The nanocatalyst can be recycled and reused several times with no remarkable loss of activity.

, p. 196 - 212 (2018/11/24)
A novel method for the one-pot synthesis of 5-substituted 1H-tetrazoles and Benzamide from arylhalide containing in situ CN insertion from inorganic salt source was accomplished in presence of a new magnetically catalyst, palladium on surface-modified Schiff-Base complex. K2[Ni(CN)4] plays a role of nontoxic inorganic cyanide source in arylhalide Nucleophilic substitution. The synthesized Pd-Schiff-Base@Fe3O4MNPs was characterized by various techniques such as FT-IR, TGA, SEM, VSM, XRD, TEM, ICP-AES, EDX, BET and XPS. The nano structure catalyst was easily recovered by external magnetic field and reused several times without noticeable loss of its catalytic activity. Leaching study of Pd-Schiff-Base@Fe3O4 MNPs shows palladium strong bonded to different active parts of catalyst surface. Heterogeneity of this catalyst has been examined using hot filtration and ICP-AES techniques.

We employ a linear linker molecule consisting of a benzene functionalised with two tetrazole moieties at para positions. Its self-assembly and coordination with the native silver adatoms and codeposited Fe adatoms on a Ag(111) surface under ultra high vacuum conditions are investigated by means of scanning tunnelling microscopy and X-ray photoelectron spectroscopy. We discover a rich spectrum of room-temperature stable Ag and Fe2+ coordination nodes depending on the formation temperature.

, p. 1293 - 1300 (2017/12/26)
5-Substituted 1 H -tetrazoles were effectively synthesized from aldoximes and diphenyl phosphorazidate (DPPA) under reflux conditions in xylenes. Various aldoximes underwent the cycloaddition reaction to afford the corresponding 5-substituted 1 H -tetrazoles in short reaction times and in good yields. Chiral aldoximes derived from amino acids also gave aminotetrazoles with almost no racemization.
Utilization of ultrasonic irradiation as green and effective one-pot protocol to prepare a novel series of bis-2-amino-1, 3, 4-oxa(thia)diazoles and bis-tetrazoles

, p. 327 - 340 (2017/12/06)
In an effective and straightforward conversion, bis-semicarbazones and bis-thiosemicarbazones are transformed into a diversity of novel substituted bis-2-amino-1, 3, 4-oxadiazoles and bis-2-amino-1, 3, 4-thiadiazoles, respectively under ultrasonic irradiation. Bis-tetrazoles are obtained from the dialdehydes by sequential reaction with hydroxylamine hydrochloride, phosphorus pentoxide and sodium azide without isolation of the intermediates oximes and nitriles. All the reactions proceed cleanly and smoothly under mild conditions, with short reaction times and broad functional groups possibility. No side reactions were observed.
