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.

Reaction conditions facilitating the site-selective direct aryl functionalisation at the C-8 position of adeninenucleosides have been identified. Many different aromatic components may be effectively cross-coupled to provide a diverse array of arylated adeninenucleoside products without the need for ribose or adenine protecting groups. The optimal palladium catalyst loading lies between 0.5 and 5 mol %

usually difficult due to their inherent complex structures. In this study, we report a poststage synthetic protocol for accessing novel ADP-2″-deoxyribosyl derivatives through designing a light-induced biomimetic reaction, and SPR assays revealed effective binding of ADP-2″-deoxyribosyl peptides to MacroH2A1.1 with a high affinity (KD = 3.75 × 10–6 M).
