“…Although 1,3‐dipolar cycloadditions between azides and norbornadiene (to provide exo‐Δ 2 −1,2,3‐triazolines) are approaching quinquagenarian status (and similar reactions are much older), there has been little investigation into their application toward polymer synthesis. In fact, reports detailing its use in this regard are quite sparse .…”

“…The roots of the strain-promoted azide cycloadditions precede the Huisgen era and date back to when Alder and Stein discovered that dicyclopentadiene reacted considerably faster than cyclopentadiene in reactions with azides. [189,190] Studies on strained alkenes and alkynes continued through the 1960s, and during this time, Wittig and Krebs reported that cyclooctyne, the smallest stable cycloalkyne, reacted "like an explosion" when combined with phenylazide. [191] Building on this classic literature, we synthesized a biotin conjugate of cyclooctyne 13 and demonstrated that it labeled azides effectively within cell-surface glycans with no apparent cytotoxic effects.…”

“…Die Geschichte der spannungskatalysierten Azid-Cycloadditionen reicht zurück bis zur Feststellung von Alder und Stein, dass bei Reaktionen mit Aziden Dicyclopentadien beträchtlich schneller reagiert als Cyclopentadien. [189,190] Studien mit gespannten Alkenen und Alkinen wurden in den 1960er Jahren fortgesetzt, und während dieser Zeit beschrieben Wittig und Krebs, dass Cyclooctin, das kleinste stabile Cycloalkin, "explosionsartig" reagierte, als es mit Phenylazid vermischt wurde. [191] Auf dieser klassischen Literatur aufbauend, synthetisierten wir ein Biotinkonjugat von Cyclooctin 13 und wiesen nach, dass es Azide in Zelloberflächenglycanen tatsächlich ohne erkennbare cytotoxische Wirkungen markierte.…”
