Synthesis of new multitope tetrazole-containing ligands

Журнал Белорусского государственного университета: Химия, 2022
Drawing the experience of 5-phenyl- and 5-pyridyltetrazoles, it was shown that classical nitration-reduction methods in combination with typical alkylation reactions of tetrazole derivatives can be used to obtain multitopic polynuclear tetrazole ...

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

Acta 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

Concise Synthesis of Tetrazole Macrocycle [PDF]

Organic Letters, 2017
A concise two step synthesis of tetrazole containing macrocycles from readily accessible starting materials is presented. The first step comprises a chemoselective amidation of amino acid derived isocyanocarboxylicacid esters with unprotected symmetrical diamines to afford diverse α-isocyano-ω-amines. In the second step, the α-isocyano-ω-amines undergo

Development of fatty acid analogues with potent anabolic effects on bone in male mice [PDF]

Bone Reports
Natural fatty acids are inhibitory to osteoclastogenesis, but only mildly so, as reported earlier by our and other groups. To improve the potency, we have synthesized two categories of analogues based on the backbone of saturated palmitic acid by ...

The Jekyll and Hyde Nature of Tetrazoles in Polymer Science: From Intrinsic Electronic Duality to Programmable Macromolecular Function. [PDF]

Angew Chem Int Ed Engl
Tetrazoles are reframed as substitution‐programmable heterocycles rather than static functional groups in polymer chemistry. By linking electronic identity to synthetic strategy and polymer architecture, this mini‐review establishes a design framework for translating tetrazole duality into predictable macromolecular function.
