Highly Effective Synthesis of C-5-Substituted 2′-Deoxyuridine Using Suzuki-Miyaura Cross-Coupling in Water
Résumé
An efficient protocol to provide a series of C-5-substituted 2′-deoxyuridine derivatives using a palladium-catalyzed Suzuki-Miyaura cross-coupling reaction in water has been established. Starting from 2′-deoxyuridine derivatives, the target nucleoside analogues were obtained in good yields with low levels of palladium loading without protection of any hydroxyl group of the glycone moiety.
