Quicker and slicker: An efficient metal‐free 1,3‐dipolar cycloaddition of dibenzocyclooctynes with nitrones proceeded with rate constants of up to 39 M−1 s−1, or up to 300 times faster than similar reactions with azides. This strategy is useful for the site‐specific N‐terminal modification of peptides and proteins (see scheme).

A new class of bioorthogonal reagents based on the cyclopentadiene scaffold is described. The diene 6,7,8,9-tetrachloro-1,4-dioxospiro[4,4]nona-6,8-diene (a tetrachlorocyclopentadiene ketal, TCK) is ambiphilic and self-orthogonal with remarkable stability. The diene reacts rapidly with a trans-cyclooctene and an endo-bicyclononyne, but slowly with dibenzoazacyclooctyne (DIBAC), allowing for tandem
A Dibenzoazacyclooctyne as a Reactive Chain Stopper for [2]Rotaxanes

A strained dibenzoazacyclooctyne (DIBAC) derivative was introduced for the preparation of a rotaxane by strain-promoted azide–alkyne cycloaddition (SPAAC), also referred to as a copper-free click reaction. The DIBAC can efficiently act as a bulky reactive chain stopper to transform a pseudorotaxane architecture consisting of a diazo-functionalized dialkoxynaphthalene guest and a tetracationic cycl
