systems 1 and 2 were prepared and then used as substrates to explore S(N)Ar and F-B displacement reactions. Chloride was easily displaced from 1 by a piperidine/ester, methylmagnesium bromide selectively displaced fluoride, and cyanide could attack both sites. System 2 readily added soft nucleophiles to the electrophilic carbon atoms, providing a new method for bioconjugation of BODIPYs to proteins while
制备了新的 BODIPY 系统 1 和 2,然后用作底物来探索 S(N)Ar 和 FB 置换反应。氯化物很容易被哌啶/酯从 1 置换,甲基溴化镁选择性置换氟化物,氰化物可以攻击两个位点。系统 2 很容易将软亲核试剂添加到亲电碳原子中,为 BODIPY 与蛋白质的生物偶联提供了一种新方法,同时还引入了 (19)F 探针。
