An efficient protocol for the construction of C-6-(hetero)aryl-substituted uridine phosphonate analogues utilizing an aerobic, ligand-free SuzukiâMiyaura cross-coupling reaction of a 6-iodo-precursor in aqueous media has been established. The method presents a modular approach toward the target compounds as demonstrated by the synthesis of a small library comprising 14 novel nucleoside phosphonates.

Sugar-protected 6-halouridine derivatives underwent Suzuki–Miyaura cross-coupling reactions with arylboronic acids in the presence of palladium(II) acetate as a catalyst, triphenylphosphine as a ligand, and sodium carbonate as a base. This methodology is applicable to both the C5- and C6-position of uridine and provides a direct access for versatile uridine derivatives.
