nevertheless suggested as the intermediate in the observed redox reaction. The relationship of this to the Mitsunobureaction, which absorbs the components of water evolved in the conversion of alcohol and carboxylic acid to ester, with desirable inversion at the alcohol carbon, is discussed. This enables a modified Mitsunobureaction, with tetrazine replacing EtO2CN=NCO2Et (DEAD), which has the advantage

allylic substituted trans-cyclooctene linker and a tetrazine activator has enabled exceptional control over chemical and biological processes. Here we report the development of a newbioorthogonal cleavage reaction based on trans-cyclooctene and tetrazine, which allows the use of highly reactive trans-cyclooctenes, leading to 3 orders of magnitude higher click rates compared to the parent reaction

typically re-lies on linkers that can negatively impact the physiochemical properties of conjugates. Cross-coupling with arylboronic acids and a new reagent, 3-((p-biphenyl-4-ylmethyl)thio)-6-methyltetrazine (b-Tz), proceeds under mild, PdCl2(dppf)-catalyzed conditions to introduce minimal, linker-free te-trazine functionality. Safety considerations guided our design of b-Tz which can be prepared on decagram

Disclosed is a liposome, comprising a lipid bilayer enclosing a cavity, wherein the bilayer comprises a channel protein releasably linked to an eight-membered non-aromatic cyclic alkenylene group, preferably a cyclooctene group, and more preferably a trans-cyclooctene group. The liposomes are used in a kit comprising the liposome, the liposomal membrane of which comprises a channel protein linked to a Trigger, and an Activator for the Trigger, wherein the Trigger comprises the eight- membered non-aromatic cyclic alkenylene group, and the Activator comprises a diene.
