The use of unprotected carbohydrate-derived nitrones as partners in strain-promotedalkyne-nitronecycloadditions was investigated as a new tool for bioconjugation. The observed second-order reactions displayed rate constants of 3.4 × 10–4–5.8 × 10–2 M–1 s–1, which is the common order of magnitude of reaction kinetics with other simple aliphatic or aromatic nitrones. Applicability of this method to
研究了使用未受保护的碳水化合物衍生的硝酮作为菌株促进的炔-硝酮环加成反应中的伙伴作为生物共轭的新工具。观察到的二级反应显示速率常数为 3.4 × 10 –4 –5.8 × 10 –2 M –1 s –1 ,这是其他简单脂肪族或芳香族硝酮反应动力学的常见数量级。通过执行一锅方案证明了该方法对水性介质的适用性,该方案结合了硝酮的顺序形成以及与水中的环辛炔的环加成。
