Flash Vacuum Pyrolysis of Azides, Triazoles, and Tetrazoles.

open access: yesChemical Reviews, 2017
Flash vacuum pyrolysis (FVP) of azides is an extremely valuable method of generating nitrenes and studying their thermal rearrangements. The nitrenes can in many cases be isolated in low-temperature matrices and observed spectroscopically. NH and methyl,

Diverse reactivity of maleimides in polymer science and beyond

open access: yesPolymer International, Volume 74, Issue 4, Page 296-306, April 2025.
This mini‐review provides a thorough overview of maleimide chemistry, highlighting its diverse reactivity in polymer and materials science applications. Abstract Maleimides are remarkably versatile functional groups, capable of participating in homo‐ and copolymerizations, Diels–Alder and (photo)cycloadditions, Michael additions, and other reactions ...

Cooperative Photometallobiocatalysis: Nonheme Fe Enzyme‐Catalyzed Enantioconvergent Radical Decarboxylative Azidation, Thiocyanation, and Isocyanation of Redox‐Active Esters

open access: yesAngewandte Chemie, Volume 137, Issue 29, July 14, 2025.
Through the directed evolution of an underexploited nonheme Fe extradiol dioxygenase, we developed a unified cooperative photobiocatalytic strategy to allow for three types of enantioconvergent radical transformations, including azidation, thiocyanation, and isocyanation.

Polymethylenetetrazole: Synthesis, Characterization, and Energetic Properties

open access: yesMolecules
The tetrazole moiety remains one of the most interesting scaffolds in the development of new high-energy density materials (HEDMs) because of its desired characteristics, such as high nitrogen content and heat of formation (HOF).

In Vitro Studies of Chromone-Tetrazoles against Pathogenic Protozoa, Bacteria, and Fungi

open access: yesMolecules, 2015
In vitro studies to fourteen previously synthesized chromone-tetrazoles and four novel fluorine-containing analogs were conducted against pathogenic protozoan (Entamoeba histolytica), pathogenic bacteria (Pseudomonas aeruginosa, and Staphylococcus aureus)

A high‐resolution data set of fatty acid‐binding protein structures. II. Crystallographic overview, ligand classes and binding pose

open access: yesActa Crystallographica Section D, Volume 81, Issue 8, Page 436-450, August 2025.
A high‐quality set of 229 crystal structures of various isoforms of human and mouse fatty acid‐binding proteins in apo and ligand‐bound forms is presented. Many ligands have associated affinity data, which may help in the development of affinity‐ and pose‐predicting algorithms.Fatty acid‐binding protein isoforms 4 and 5 are potential diabetes and ...

Silica Sulfuric Acid as an Efficient Heterogeneous Catalyst for the Solvent-Free Synthesis of 1-Substituted 1H-1,2,3,4-Tetrazoles

open access: yesJournal of Chemistry, 2013
Silica sulfuric acid (SSA) was found to be an efficient heterogeneous catalyst for the synthesis of 1-substituted 1H-1,2,3,4-tetrazoles from the reaction of primary amines with triethyl orthoformate and sodium azide under thermal and solvent-free ...

Tetrazoles of manno- and rhamno- furanoses

open access: yesTetrahedron, 1999
Abstract The synthesis of [3.3.0] bicyclic tetrazoles derived from D-manno and D-rhamnofuranose starting from D-mannose, and of L-rhamnofuranose starting from L-rhamnose is described. The key step in the formation of all three examples of this novel class of sugar mimics is an intramolecular [1,3]-dipolar cycloaddition of azide and nitrile moieties.

A high‐resolution data set of fatty acid‐binding protein structures. III. Unexpectedly high occurrence of wrong ligands

open access: yesActa Crystallographica Section D, Volume 81, Issue 8, Page 451-464, August 2025.
Very high‐resolution fatty acid‐binding protein structures identified a substantial number of ligands that differ strongly from their expected structure. If different ligand chemistry is a potentially overlooked problem in other, lower resolution, crystal structures of protein–ligand complexes, it has repercussions for any study using such structures ...

A high‐resolution data set of fatty acid‐binding protein structures. I. Dynamics of FABP4 and ligand binding

open access: yesActa Crystallographica Section D, Volume 81, Issue 8, Page 423-435, August 2025.
NMR studies on human FABP4 in solution and bound to micelles and bicelles delineate its dynamics in a ligand‐dependent fashion. Residual ligands are co‐purified with the protein, which may negatively influence binding studies with low‐affinity ligands.Fatty acid‐binding proteins (FABPs) are involved in the uptake and intracellular trafficking of fatty ...
