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

Vinylboronic acids (VBAs) are stable, unstrained bioorthogonal reactants in tetrazine ligation. Fast reaction rates are obtained for tetrazines containing a coordinating substituent, whereas VBAs lacking a Lewis basic substituent are unreactive. We explored the molecular basis of the unique reactivity of VBAs and demonstrate the scope in the simultaneous orthogonal tetrazine labelling of two proteins
Disclosed is the use of the reactive components of the inverse electron-demand Diels Alder reaction for chemical masking and unmasking in vitro. This can be applied in complex chemical reactions and, particularly in the synthesis of biomolecules, e.g. on solid supports. The reactive components are a dienophile, particularly a trans-cyclooctene, and a diene, particularly a tetrazine.

self-assembly to target overexpressed alkaline phosphatases in cancer cells and bioorthogonal reactions for controllable extracellular and intracellular activation of RuII-based imaging probes and photosensitizers is presented. The emission enhancement, lifetime extension, and (photo)cytotoxicity of the resulting RuII supramolecularassemblies were explored extracellularly and intracellularly.
