ortho-Lithiation followed by electrophilic trapping of N-unsubstituted and N2-triphenylmethyl substituted 5-aryltetrazoles, further substituted with another ortho-director at the para position of the aryl ring, resulted in the formation of regioisomers of

A series of 5-(o-tolyl)-1H-tetrazole derivatives were synthesized and evaluated for their anticonvulsant activities. 1-(2-Methylbenzyl)-5-(o-tolyl)-1H-tetrazole (3h) showed important anticonvulsant activity against the MES-induced seizures, as well as low

[Figure not available: see fulltext.] The reaction of 5-aryl-NH-tetrazoles with adamantan-1-ol in concentrated sulfuric acid proceeds regioselectively with the formation of the corresponding 2-adamantyl-5-aryl-2H-tetrazoles. Nitration of these compounds l

A mild, direct C-H arylation of 1-substituted tetrazoles to 5-aryltetrazoles is developed using a Pd/Cu cocatalytic system with readily available aryl bromides. The methodology avoids late-stage usage of azides and tolerates a wide range of functionalities.
A robust and recyclable ionic liquid-supported copper(II) catalyst for the synthesis of 5-substituted-1H-tetrazoles using microwave irradiation

Abstract: A novel and robust ionic liquid-supported copper(II) catalyst has been developed and explored for the efficient synthesis of 5-substituted-1H-tetrazoles using microwave irradiation. The ionic liquid-supported catalyst facilitated the efficient isolation of tetrazole products with high purity by simple extraction with organic solvent. Recovered ionic liquid-supported copper(II) catalyst could be recycled for three times for the synthesis of tetrazole products with high purity. This synthetic protocol offers a very clean, convenient, and microwave-assisted environment-friendly method for the efficient synthesis of 5-substituted-1H-tetrazoles with high yield.

2,5-Diaryltetrazoles are a diverse range of compounds of considerable interest within the field of photochemistry as a valuable precursor of the nitrile imine 1,3-dipole. Current literature approaches toward this heterocycle remain unsuitable for the prac
Facile one-pot preparation of 5-aryltetrazoles and 3-arylisoxazoles from aryl bromides
Kobayashi, Eiji,Togo, Hideo
, p. 4226 - 4235 (2018/07/06)
The successive treatment of aryl bromides with n-BuLi, DMF, hydroxylamine hydrochloride, and finally diphenylphosphoryl azide provided efficiently the corresponding 5-aryltetrazoles in good to moderate yields. Similarly, the successive treatment of aryl bromides with n-BuLi, DMF, hydroxylamine hydrochloride, and finally diethyl acetylenedicarboxylate and Oxone provided efficiently the corresponding diethyl 3-arylisoxazole-4,5-dicarboxylates in good to moderate yields. Aromatic aldoximes are the key intermediates in both reactions, and 5-aryltetrazoles and 3-arylisoxazoles could be obtained from aryl bromides in one pot under transition-metal-free conditions.

5-Aryl-1H-tetrazoles (1–24) were synthesized and screened for their xanthine oxidase (XO) inhibitory activity using allopurinol as standard inhibitor (IC50 = 2.0 ± 0.01 μM). Six compounds 3, 4, 5, 9, 21, and 24 exhibited significant to weak act

The magnetically separable catalysts are used in the synthesis of N-containing heterocycles, including tetrazoles, triazoles, and imidazolines. The magnetic silica sphere grafted sulfonic acid (MSS-SO3H) is suitable for the synthesis of 1,2,3-triazole via the cycloaddition of nitroalkene with NaN3, whereas the zinc-modified silica sphere catalyst (MSS-SO3Zn) is more suitable for the synthesis of tetrazoles. The MSS-SO3Zn catalyst also works well for the synthesis of 2-substituted imidazoline via the condensation of nitriles with ethylenediamine. Both of the MSS-SO3H and MSS-SO3Zn catalysts can be recovered easily by a magnet, and they can be reused without further tedious activation.
