Coupling reactions, suitable for use in organic or aqueous media, are performed by contacting a 1,2,4,5-tetrazine with a dienophile. The dienophile may be covalently bonded to a protein, and the coupling reaction may be performed in biological media such as those containing cells or cell lysates. The reactions may be performed in the presence of primary amines, thiols, acetylenes, azides, phosphines, and products of Staudinger and/or Sharpless-Huisgen reactions Novel 3-substituted cyclopropene compounds and trans-cyclooctenes are exemplary dienophiles for these reactions.

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 reactice components are a dienophile, particularly a trans-cyclooctene, and a diene, particularly a tetrazine.

Disclosed is a kit for the administration and activation of a Prodrug. The kit comprises a Masking Moiety linked, directly or indirectly, to a Trigger moiety, which in turn is linked to a Drug, and an Activator for the Trigger moiety. The Trigger moiety comprises a dienophile and the Activator comprises a diene, whereby the dienophile is an eight-membered non- aromatic cyclic alkenylene group, preferably a cyclooctene group, and more preferably a trans-cyclooctene group. The Trigger and the Activator undergo a fast, bio-orthogonal reaction resulting in the release of the Masking Moiety, and activation of the drug.
