Abstract
A CuI/KF mediated perfluoroalkylation reaction of various 9-substituted 6-iodopurines 1 with trimethyl(trifluoromethyl)silane or heptafluoropropyl(trimethyl)silane was used for the synthesis of the corresponding 6-(trifluoromethyl)- and 6-(heptafluoropropyl)purine derivatives (purine bases, nucleosides and acyclic nucleotide analogues) in moderate to good yields.
Keywords: Purines; Nucleosides; Cross-coupling reactions; Trifluoromethylation; Perfluoroalkylation; Cuprates; Fluorinated compounds; Cytostatic activity.
