5-lodouracil and 6-iodopurine derivatives readily insert zinc dust (25 °C or 70 °C) in THF or DMAC affording zincated nucleic acid base derivatives which undergo efficient palladium catalyzed cross-coupling reactions with aryliodides in good yields. This reaction sequence has been extended to two nucleosides (a purine and an uridine derivative).
