制备方法与用途

简介

2-羟基-6-三氟甲基吡啶在常温常压下为白色或灰白色的固体粉末状。这是一种常用的有机合成子,文献中常见其以互变异构体酮的形式出现,而非单纯吡啶羟基形式。该化合物在醚类溶剂中的溶解性一般,在水中的溶解度较低。它可用作有机合成的中间体。

用途

2-羟基-6-三氟甲基吡啶常作为有机合成中间体使用。通常情况下,其以烯醇式结构参与后续转化;在碘甲烷保护作用下,可以得到羟基被甲基保护的产物,且该甲氧基产物依然保留着吡啶环的结构。此外,由于其烯醇式的结构特征,在二氧化铂催化的作用下,吡啶环可以进行氢化反应,生成内酰胺产品。

合成方法

合成2-羟基-6-三氟甲基吡啶的主要方法是从2-氯-6-三氟甲基吡啶出发,通过将氯原子替换为羟基的方式得到目标产物。这一过程通常需要在高温和强碱的条件下进行。此外,有文献报道了另一种方法,即通过将羧基转化为氟化物来合成三氟甲基化的吡啶产品。

    功能化环烯烃配体作为 Catellani 型反应中邻位约束的解决方案
    摘要:
    Catellani 反应,即 Pd/降冰片烯 (NBE) 催化,已通过卤代芳烃的邻位官能化/自身终止过程演变成一种多取代芳烃的通用方法。尽管在过去 25 年取得了重大进展,但该反应在卤代芳烃的取代模式(称为“邻位约束”)方面仍然存在内在限制。当不存在邻位取代基时,底物通常无法进行有效的单邻位官能化过程,并且邻位-双功能化产物或嵌入 NBE 的副产物占主导地位。为了应对这一挑战,已经开发出结构改性的 NBE (smNBE),这些 NBE 被证明对邻位未取代的卤代芳烃的单邻位氨基化、酰化和芳基化 Catellani 反应有效。然而,这种策略无法解决邻位烷基化Catellani 反应中的邻位约束,并且迄今为止,对于这种具有挑战性但综合有用的转化,缺乏通用的解决方案。最近,我们小组开发了 Pd/烯烃催化,其中无应变的环烯烃配体作为共价催化模块,使邻位反应成为可能。-不含 NBE 的烷基化 Catellani
