The synthesis of 2′-deoxy-2′-fluoro-β-d-arabinofuranosyl nucleosides (1b, 2b, and 3b) were described and their conformation in solution as well as in the solid state was determined. In addition to this, building blocks 10a,b and 13a,b were prepared and employed in solid-phase oligonucleotide synthesis. For compounds 1a and 1b the lactime proton is protected to avoid unresolved degradation of its phosphoramidites
描述了 2'-脱氧-2'-氟-β-d-阿拉伯呋喃糖基核苷(1b、2b 和 3b)的合成,并确定了它们在溶液和固态中的构象。除此之外,还制备了结构单元 10a、b 和 13a、b 并将其用于固相寡核苷酸合成。对于化合物 1a 和 1b,内酰胺质子被保护以避免其亚磷酰胺 10a、b 未解决的降解。已进行紫外线熔化研究以评估含有化合物 1a、b 和 3a、b 的寡核苷酸的热稳定性。
