  Efficient Synthesis of 1-Deaza-6-methoxypurine-N9-β-2′-deoxyribonucleoside and Related DNA Building Blocks

  摘要：

  An improved synthesis of the 2'-deoxyribonucleoside containing 1-deaza-6-methoxypurine as artificial nucleobase is described. By optimizing the conditions for the deprotection of p-toluoyl-protected 1-deaza-6-nitropurine 2'-deoxyribonucleoside, the isolated yield of the title compound could be increased from 15% to 90%. In addition, the synthesis and characterization of the corresponding 5'-(4,4'-dimethoxytrityl) (DMT) protected phosphoramidite, a potentially useful building block for the synthesis of artificial oligonucleotides, is reported. The title compound offers interesting hydrogen bond donor and metal-binding properties for its application in metal-mediated base pairs.
