Aryl carboxylic acids represent an important class of structural motifs ubiquitous in pharmaceutically active molecules and are ideal targets for the installation of a radioactive tag employing isotopically labelled CO<sub>2<\/sub>. However, direct isotope incorporation via the reported catalytic reductive carboxylation (CRC) of aryl electrophiles relies on excess CO<sub>2<\/sub>, which is incompatible with carbon-14 isotope incorporation. Furthermore, the application of some CRC reactions for late-stage carboxylation is limited because of the low tolerance of molecular complexity by the catalysts. Herein, we report the development of a practical and affordable Pd-catalysed electrocarboxylation setup. This approach enables the use of near-stoichiometric\u00a0<sup>14<\/sup>CO<sub>2<\/sub>\u00a0generated from the primary carbon-14 source Ba<sup>14<\/sup>CO<sub>3<\/sub>, facilitating late-stage and single-step carbon-14 labelling of pharmaceuticals and representative precursors. The proposed isotope-labelling protocol holds significant promise for immediate impact on drug development programmes.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Find a list of publications by\u00a0NordCO<sub>2<\/sub>\u00a0members on our\u00a0<a href=\"https:\/\/site.uit.no\/nordco2\/publications\/\">Publications<\/a>\u00a0page\u00a0\ud83d\ude42<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Title:Efficient palladium-catalyzed electrocarboxylation enables late-stage carbon isotope labelling Abstract:Carbon isotope labelling of bioactive molecules is essential for accessing the pharmacokinetic and pharmacodynamic properties of new &hellip;<\/p>\n","protected":false},"author":514,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"image","meta":{"ngg_post_thumbnail":0,"footnotes":""},"categories":[8],"tags":[],"class_list":["post-3443","post","type-post","status-publish","format-image","hentry","category-research","post_format-post-format-image"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.8 -
