Development of a 11C-labeled tetrazine for rapid tetrazine–trans-cyclooctene ligation

Chemical Communications, 2013
Tetrazine-trans-cyclooctene ligations are remarkably fast and selective reactions even at low micro-molar concentrations. In bioorthogonal radiochemistry, tools that enable conjugation of radioactive probes to pre-targeted vectors are of great interest.

BODIPY‐Tetrazine Multichromophoric Derivatives

European Journal of Organic Chemistry, 2010
AbstractNew dyes based on BODIPY and tetrazine fluorophores connected through a phenyl spacer have been synthesized and their absorption, emission and electrochemical properties characterized. BODIPY can be reversibly oxidized into a stable cation radical whereas tetrazine can be reduced to a stable anion radical.

Streamlining Tetrazine Synthesis

Chemical & Engineering News Archive, 2012
Facile synthesis of promising tetrazine biochemical probes could be a big step forward for researchers who examine biochemistry as it happens in cells and live animals (Angew. Chem. Int. Ed., DOI: 10.1002/anie.201201117). The advance, utilizing Lewis acid catalysts, might allow more researchers to make the probes in one pot from commercially available ...

Unusual Investigation of Polycyclic Saturated Tetrazine: A Breakthrough to 1,2,4,5‐Tetrazine

Journal of Heterocyclic Chemistry, 2015
The theoretical investigation of polycyclic saturated tetrazine is a novel process, and the reaction of 1,2,4,5‐tetrazine with diazomethane that undergoes polymerization reaction has been studied by using a computational method, and it gives dinitrogen (N2) as the major product. The spectroscopic studies, bond length, bond angle, heat of formation, and
