Abstract:
In this study, we report the bioorthogonal cleavage of physiologically stable methylene tetrazines bearing an ether or ester linkage in the presence of trans-cyclooctene. Based on this approach, molecules with phenol or carboxylic acid moieties were efficiently released in a controlled manner, which can be effectively applied in living cells. We expect this bioorthogonal cleavage approach can be applied to several biomedical applications, including the development of antibody-drug conjugates, pretargeted prodrug release, and protein activation.

Thermal Electrocyclic Reactions: Stereochemistry
Selection Rules: Thermal Activation
Conjugated systems containing an even number of π-electron pairs undergo a conrotatory ring closure. For example, thermal electrocyclization of (2E,4E)-2,4-hexadiene, a conjugated diene containing two π-electron pairs, gives trans-3,4-dimethylcyclobutene.

Preparation of Epoxides
Epoxides result from alkene oxidation, which can be achieved by a) air, b) peroxy acids, c) hypochlorous acids, and d) halohydrin cyclization.
Epoxidation with Peroxy Acids
Epoxidation of alkenes via oxidation with peroxy acids involves the conversion of a carbon–carbon double bond to an epoxide using the oxidizing agent meta-chloroperoxybenzoic acid, commonly known as MCPBA. Since the O–O bond of peroxy acids is very weak, the addition of electrophilic oxygen of...
