A copper-catalyzed procedure enabling dynamic carbon isotope exchange is described. Utilizing the universal precursor [14C]CO2, this protocol allows to insert, in one single step, the desired carbon tag into carboxylic acids with no need of structural modifications. Reducing synthetic costs and limiting the generation of radioactive waste, this procedure will facilitate the access to carboxylic acids
描述了一种能够实现动态碳同位素交换的铜催化过程。利用通用前体 [14C]CO2,该协议允许在一个步骤中将所需的碳标签插入到羧酸中,而无需进行结构修改。该程序降低了合成成本并限制了放射性废物的产生,将有助于获得含羧酸的药物,并加速支持药物开发的早期基于 14C 的 ADME 研究。
