biologically relevant compounds need to be developed. Furans are frequently encountered in bioactive molecules, and a good synthesis of labeled furan is found in the literature. We required a relatively uncommon labeled furan, 5-chloro-2-furoic acid, for investigative work labeled with C-13 and C-14. Carboxylation of the lithium anion of [13C4]furan with 13CO2 followed by chlorination using benzyltrimethylammonium
标记化合物及其制备方法的清单不断增加,但仍需要开发更多的生物相关化合物的构建模块。呋喃在生物活性分子中经常遇到,并且在文献中发现了标记呋喃的良好合成。我们需要一种相对不常见的标记呋喃,5-氯-2-呋喃酸,用于标记为 C-13 和 C-14 的调查工作。[13C4]呋喃的锂阴离子用 13CO2 羧化,然后用二氯碘酸苄基三甲基铵氯化,得到中等产率和高纯度的目标化合物。然后用未标记的呋喃和 14CO2 重复相同的程序,得到[羰基-14C]-5-氯呋喃-2-羧酸。版权所有 © 2010 John Wiley & Sons, Ltd.
