Regioselectivity of the C-Metalation of 6-Furylpurine: Importance of Directing Effects
We report the C-metalation of 6-furylpurhie with Pt2+, Pd2+, and Hg2+. The ligand binds the metal ions in a bidentate fashion, involving the N7 purine atom and one of the furyl carbon atoms. The regioselectivity is determined by the metal ion. Pt2+ and Pd2+ coordinate the furyl moiety in its beta position and Hg2+ in its electronically preferred alpha position.
