The present application relates to functionalized 1,2,4,5-tetrazine compounds. The compounds are useful in compositions and methods using bioorthogonal inverse electron demand Diels-Alder cycloaddition reactions for the rapid and specific covalent delivery of a "payload" to a ligand bound to a biological target.
A facile, efficient and metal‐free synthetic approach to 3‐monosubstituted unsymmetrical 1,2,4,5‐tetrazines is presented. Dichloromethane (DCM) is for the first time recognized as a novel reagent in the synthetic chemistry of tetrazines. Using this novel approach 11 3‐aryl/alkyl 1,2,4,5‐tetrazines were prepared in excellent yields (up to 75 %). The mechanism of this new reaction, including the role

cleavage of a protecting group from a protein or drug under bioorthogonal conditions enables accurate spatiotemporal control over protein or drug activity. Disclosed herein is that vinyl ethers serve as protecting groups for alcohol‐containing molecules and as reagents for bioorthogonal bond‐cleavage reactions. A vinyl ether moiety was installed in a range of molecules, including amino acids, a monosaccharide
