Described herein are tetrazine derivatives and efficient synthetic methods of synthesis thereof using elimination-Heck cascade reaction. Provided herein is the synthesis of conjugated tetrazines from the tetrazine derivatives. Also provided herein are methods of use of the conjugated tetrazines as fluorogenic probes for live-cell imaging.
growing application of tetrazine bioorthogonal chemistry, it is still challenging to access tetrazines conveniently from easily available materials. Described here is the de novo formation of tetrazine from nitriles and hydrazine hydrate using a broad array of thiol‐containing catalysts, including peptides. Using this facile methodology, the syntheses of 14 unsymmetric tetrazines, containing a range of

biological functional group and are widely used for chemical modification of biomolecules. Recently, we reported that vinylboronic acids (VBAs) gave exceptionally high reaction rates in the bioorthogonal inverse electron-demand Diels-Alder (iEDDA) reaction with tetrazines bearing a boron-coordinating pyridyl moiety compared to tetrazines lacking such a substituent. In this integrated experimental and theoretical

ethynyl-triazolyl-phosphinates (ETPs) were discovered as modular and cysteine-selective electrophiles for bioconjugation. Using CuI-click chemistry in aqueous buffers, this functional group can be easily introduced into azide-containing (bio-)molecules. These reagents can be used for proteome-wide cysteine profiling and to obtain functional peptide- and protein conjugates, as well as protein–protein conjugates
