Fluoro, Alkylsulfanyl, and Alkylsulfonyl Leaving Groups in Suzuki Cross-Coupling Reactions of Purine 2‘-Deoxynucleosides and Nucleosides
摘要:
[GRAPHICS]Protected 2'-deoxynucleoside and nucleoside derivatives of 6-fluoropurine, 6-(3-methylbutyl)sulfanylpurine, and 6-(3-methylbutyl)ylsulfonyipurine undergo nickel- or palladium-mediated C-C cross-coupling with arylboronic acids to give good yields of 6-arylpurine products.
