Synthesis of 4-[10H-Phenothiazin-10-yl(1H-tetrazol-5-yl)-methyl]phenol

open access: yesMolbank, 2009
This present work aims at synthesizing a novel tetrazole from phenothiazine. Phenothiazine is converted into a nitrile by reacting it with 4-hydroxybenzaldehyde, sodium metabisulphite and sodium cyanide. The nitrile on treatment with NaN3/DMF yielded the

1-(2,2-Diphenylethyl)-1H-tetrazole

open access: yesActa Crystallographica Section E, 2012
The crystal structure of the title compound, C15H14N4, contains chains of coplanar tetrazole rings with the chain direction along b. These are formed through weak hydrogen bonds, donated by the tetrazole H atoms and by one of the H atoms of the methylene

Direct synthesis of anomeric tetrazolyl iminosugars from sugar-derived lactams

open access: yesBeilstein Journal of Organic Chemistry, 2021
Herein we present the direct asymmetric synthesis of tetrazole-functionalized 1-deoxynojirimycin derivatives from simple sugars via a Schwartz’s reagent-mediated reductive amide functionalization followed by a variant of the Ugi–azide multicomponent ...

One-Pot Multicomponent Synthesis and Cytotoxic Evaluation of Novel 7-Substituted-5-(1H-Indol-3-yl)Tetrazolo[1,5-a] Pyrimidine-6-Carbonitrile

open access: yesMolecules, 2020
A series of novel 7-substituted-5-(1H-indol-3-yl)tetrazolo[1,5-a]pyrimidine-6-carbonitrile was synthesized via a one-pot, three-multicomponent reaction of appropriate aldehydes, 1H-tetrazole-5-amine and 3-cyanoacetyl indole in catalytic triethylamine ...

Safe and Efficient Tetrazole Synthesis in a Continuous Flow Microreactor [PDF]

open access: yes, 2011
Safer flow: The synthesis of 5-substituted tetrazoles in flow (see scheme) is safe, efficient, scalable, requires no metal promoter, and uses a near-equimolar amount of NaN[subscript 3], yet nonetheless displays a broad substrate scope.

Synthesis of selected 5-thio-substituted tetrazole derivatives and evaluation of their antibacterial and antifungal activities [PDF]

open access: yesJournal of the Serbian Chemical Society, 2011
Several 5-thio-substituted tetrazole derivatives were efficiently synthesized by a three-step process. The substituted tetrazol-5-thiol, namely, 1-benzyl-1H-tetrazole-5-thiol (2) was prepared by refluxing commercially available benzyl isothiocyanate (1 ...

Synthesis, single crystal analysis, biological and docking evaluation of tetrazole derivatives

open access: yesHeliyon, 2018
Tetrazoles are conjugated nitrogen-rich heterocycles considered as bio-isosteres of carboxylic acids. Tetrazoles owing to their conjugated structures serve as biologically relevant potent scaffolds.

Sigmatropic rearrangements in 5-allyloxytetrazoles [PDF]

open access: yes, 2011
Mechanisms of thermal isomerization of allyl tetrazolyl ethers derived from the carbocyclic allylic alcohols cyclohex-2-enol and 3-methylcyclohex-2-enol and from the natural terpene alcohol nerol were investigated.
