Pd-catalyzed direct CâH arylation of unprotected purinenucleosides with aryl iodides at position 8 was developed to allow a straightforward single-step introduction of diverse aryl groups.

Abstract Reaction conditions for the Suzuki–Miyaura cross‐coupling of unprotected halopurine nucleosides with arylboronic acids in aqueous media were investigated. A series of arylated purine nucleosides was prepared in water without an organic cosolvent, using either Pd(PPh3)4 or Pd(OAc)2/TPPTS as the catalyst.
