制备方法与用途

在医药和化工中间体的制备中，2-甲基-4-吡啶硼酸有着广泛的应用。其合成过程如下：

在氮气保护下，将四口瓶冷却至-68～-70℃后，依次加入4-溴-2-甲基吡啶、一定配比的硼酸三丁酯和四氢呋喃。随后滴加正丁基锂直至溶液变为黄色，并保温1小时。接着立即滴加稀HCl进行水解，观察到沉淀生成并逐渐消失，调节体系pH值至1。

向该溶液中加入25%的NaOH溶液，将pH值调至13，搅拌1小时后分液。有机相用10% NaOH溶液萃取15 mL，合并水相；再以15 mL THF分别萃取碱液两次。所得碱液用稀HCl调节pH值，观察到浑浊逐渐形成并出现絮状物，最终将pH调至5.0。

最后，使用70 mL四氢呋喃萃取出水相中的有机物质，旋干、提纯后得到2-甲基-4-吡啶硼酸产品，收率为82.20%。

  摘要：

  芳基硼酸作为试剂和目标结构在各种有用的应用中变得越来越重要。最近，报道了使用原子经济的四羟基二硼（BBA）试剂在钯催化下合成芳基硼酸。钯的高成本，加上钯和铜催化工艺的一些限制，促使我们开发一种替代方法。因此，已经制定了使用四羟基二硼（BBA）对芳基和杂芳基卤化物和拟卤化物进行镍催化的硼基化反应。该反应被证明具有广泛的官能团耐受性并适用于许多杂环体系。据我们所知，这里提供的例子代表了在室温下进行的唯一有效的镍催化宫浦硼化反应。
