Abstract
The palladium-catalyzed direct C-H olefination of unprotected uridine, 2'-deoxyuridine, uridine monophosphate, and uridine analogues are described here. This protocol provides an efficient, atom-economical, and environmentally friendly method for the introduction of an alkenyl group at the C5 position of the uracil without pre-functionalization. A series of C5-alkenylated uridine analogues, including some biologically significant compounds and potential pharmaceutical candidates, were synthesized with exposed hydroxyl groups on the ribose. © 2023 Wiley Periodicals LLC. Basic Protocol 1: The reaction of uridine, 2'-deoxyuridine, and sofosbuvir for the C-H olefination with methyl acrylate Basic Protocol 2: The reaction of uridine and 2'-deoxyuridine for the C-H olefination with styrene.
