用途

6-（三氟甲基）吡啶-2-甲酸是一种有机中间体，可用于制备2-（6-（三氟甲基）吡啶-2-基）乙腈等有机物。

制备

将2-溴-6-三氟甲基吡啶 (1.13 g, 5 mmol)、氰化亚铜 (0.67 g, 7.5 mmol) 和碘化钾 (1.25 g, 7.5 mmol) 悬浮在DMF (15 mL) 中，加热至130℃反应12小时。反应混合物倒入冰水 (100 mL)和乙酸乙酯 (50 mL) 的混合溶剂中。滤去固体后，用乙酸乙酯萃取 (50 mL*3)，合并有机相并用饱和食盐水洗涤，再用无水硫酸镁干燥。浓缩得到淡黄色油状物2-氰基-6-三氟甲基吡啶 (0.95 g)。

将2-氰基-6-三氟甲基吡啶 (0.95 g) 和浓盐酸HCl (37%，15 mL) 加热回流2小时。冷却后，过滤得到白色固体6-（三氟甲基）吡啶-2-甲酸 (0.70 g, 74%)。

  The present disclosure relates to bifunctional compounds, which find utility as modulators of Interleukin-1 Receptor-Associated Kinase 4 (IRAK-4); the target protein). In particular, the present disclosure is directed to bifunctional compounds, which contain on one end a Von Hppel-Lindau, cereblon, ligand which binds to the E3 ubiquitin ligase and on the other end a moiety which binds the target protein, such that the target protein is placed in proximity to the ubiquitin ligase to effect degradation (and inhibition) of target protein. The present disclosure exhibits a broad range of pharmacological activities associated with degradation/inhibition of target protein. Diseases or disorders that result from aggregation or accumulation of the target protein are treated or prevented with compounds and compositions of the present disclosure.

• Organocatalytic decarboxylative alkylation of <i>N</i>-hydroxy-phthalimide esters enabled by pyridine-boryl radicals
  作者：Liuzhou Gao、Guoqiang Wang、Jia Cao、Dandan Yuan、Cheng Xu、Xuewen Guo、Shuhua Li

  DOI：10.1039/c8cc06152a

  日期：——

  The decarboxylative alkylation of N-hydroxyphthalimide (NHPI) based reactive esters with olefins has been achieved via an organocatalytic strategy. Control experiments and density functional theory calculations suggest that these reactions involve a boryl-radical mediated decarboxylation pathway, which is different from the single electron transfer involved in decarboxylative alkylation reactions reported

  N-羟基邻苯二甲酰亚胺（NHPI）基反应性酯与烯烃的脱羧烷基化已通过有机催化策略实现。对照实验和密度泛函理论计算表明，这些反应涉及硼基自由基介导的脱羧途径，该途径不同于先前报道的脱羧烷基化反应中涉及的单电子转移。这种无金属的脱羧烷基化反应具有良好的功能相容性，并且通过烷基和芳基羧酸衍生物的转化说明了广泛的底物范围。
