  Synthesis of functionalized biphenyl-C-nucleosides and their incorporation into oligodeoxynucleotides

  摘要：

  We describe the synthesis of eight novel C-nucleosides in which the nucleobases are replaced by biphenyl residues that carry one or two electron donor (-OCH3,-NH2) or acceptor (-NO2) functional groups in the distal ring. These C-nucleosides were synthesized convergently and in high yields from a common bromophenyl-C-nucleoside precursor via Suzuki coupling with the respective boronic acids or esters. These nucleosides were subsequently converted into the corresponding phosphoramidite building blocks and efficiently incorporated into oligodeoxynucleotides by standard phosphoramidite chemistry.

• Modular Synthesis of 4-Aryl- and 4-Amino-Substituted Benzene <i>C</i>-2′-Deoxyribonucleosides

  A modular methodology for the syntheses of various 4-substituted-phenyl C-2′-deoxyribonucleosides has been developed. Coupling of toluoylated halogenose 1 with 4-bromophenylmagnesium bromide afforded the desired bis(toluoyl)-protected 1β-(4-bromophenyl)-1,2-dideoxyribofuranose 2a, which was deprotected under Zemplen conditions to give the unprotected 1β-(4-bromophenyl)-1,2-dideoxyribofuranose 3, and reprotected to give the bis(tert-butyldimethylsilyl)-protected 1β-(4-bromophenyl)-1,2-dideoxyribofuranose 4. Alternatively, addition of 1-lithio-4-bromobenzene on tert-butyldimethylsilyl-protected lactone 5, followed by reduction of the hemiketal 6, also gave bis(tert-butyldimethylsilyl)-protected bromophenyl nucleoside 4. Intermediates 2a and 4 were then subjected to a series of palladium-catalyzed cross-coupling reactions, aminations, and C-H activation to give 1β-[4-(aryl-, alkyl-, or amino)phenyl]-1,2-dideoxyribofuranoses 8a-n after deprotection. Finally, other types of 4-arylphenyl C-nucleosides 8o-u were prepared directly by aqueous-phase Suzuki cross-coupling reactions of unprotected 3 with boronic acids under microwave irradiation.
