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).
更快、更流畅:二苯并环辛炔与硝酮的高效无金属 1,3-偶极环加成反应速率常数高达 39 M -1 s -1,比使用叠氮化物的类似反应快 300 倍。该策略可用于肽和蛋白质的位点特异性 N 端修饰(参见方案)。
