A transition‐metal‐free carbon isotope exchange procedure on phenyl acetic acids is described. Utilizing the universal precursor CO2, this protocol allows the carbon isotope to be inserted into the carboxylic acid position, with no need of precursor synthesis. This procedure enabled the labeling of 15 pharmaceuticals and was compatible with carbon isotopes [14C] and [13C]. A proof of concept with [11C]
描述了在苯乙酸上无过渡金属的碳同位素交换程序。利用通用前驱体CO 2,该方案允许将碳同位素插入到羧酸位置,而无需前驱体合成。该程序可以标记15种药物,并且与碳同位素[ 14 C]和[ 13 C]兼容。还获得了具有低摩尔活性的[ 11 C]概念证明,对分布研究有价值。
