Syntheses of substituted pyridines and fluorinated compounds, which are often pharmaceutical targets, are important objectives in organic chemistry. Herein, we found that decarboxylative fluorination of lithium 2‐pyridylacetates occur under catalyst‐free conditions. The phenomenon can be applied to one‐pot transformation of substituted methyl 2‐pyridylacetate to 2‐(fluoroalkyl)pyridine by decarboxylative
取代的吡啶和氟化化合物的合成通常是药学上的目标,是有机化学中的重要目标。在这里,我们发现2-吡啶基乙酸锂的脱羧氟化反应是在无催化剂条件下进行的。该现象可用于通过中间体2-吡啶基乙酸锂的脱羧氟化作用将取代的2-吡啶基乙酸甲酯单锅转化为2-(氟代烷基)吡啶。该方法也适用于2-(二氟烷基)吡啶的合成。
