制备方法与用途

4-氨基-3-碘吡啶

4-氨基-3-碘吡啶是一种吡啶类衍生物，广泛用于合成农药和具有生物活性的分子。

制备方法

将18.8毫克（0.2毫摩尔）4-氨基吡啶、27.9毫克（0.11毫摩尔）碘以及19.5毫克（0.055毫摩尔）4-碘苯磺酸钾溶解于0.5毫升乙腈中，然后慢慢滴加5%的硫酸水溶液（0.5毫升）。将混合物在65°C下搅拌反应12小时，并通过TLC点板和GC-MS监测反应进程。反应结束后，向混合物中加入0.5毫升5%的亚硫酸钠水溶液及5毫升水，摇动5分钟后过滤沉淀物并用少量水洗涤，干燥后即可得到目标产物4-氨基-3-碘吡啶。

  铜电荷转移催化使（杂）芳基酸脱羧硼化和交叉偶联

  摘要：

  我们报告了一种用于芳基硼酸酯合成的铜催化策略，该策略利用光诱导配体到金属电荷转移 (LMCT) 将（杂）芳基酸转化为适合环境温度硼化的芳基自由基。这种近紫外过程在温和条件下发生，不需要对天然酸进行预功能化，并且广泛适用于各种芳基、杂芳基和药物底物。我们还报告了一种用于脱羧交叉偶联的一锅程序，该程序将催化 LMCT 硼酸化和钯催化的 Suzuki-Miyaura 芳基化、乙烯基化或与有机溴化物的烷基化结合起来，以获得一系列增值产品。通过开发异选择性双脱羧 C(sp 2 )–C(sp 2）偶联序列，铜催化的两种不同酸（包括药物底物）的 LMCT 硼化和卤化过程与随后的 Suzuki-Miyaura 交叉偶联配对。
