  Pteridine Nucleosides—New Versatile Building Blocks in Oligonucleotide Synthesis

  摘要：

  Chemical syntheses of 1-(2-deoxy-beta-D-ribofuranosyl)lumazines and isopterins as well as 8-(2-deoxy-beta-D-ribofuranosyl)-4-amino-7(8H)pteridones and -isoxanthopterins have been developed to make the structural analogs of the naturally occurring 2'-deoxyribonucleosides in the pteridine series available. The corresponding phosphoramidites have been used in machine-aided solid-support syntheses leading to new types of fluorescence labeled oligonucleotides. The effects of the various fluorophors on duplex formation and as labels for enzyme reactions is demonstrated.

  Various 4-amino-7(8H)pteridones (6, 12, 14, 15, 20, 22) have been glycosylated with 1-chloro-2′-deoxy-D-ribofuranose derivatives (25, 26) applying the new DBU-salt method to form the N8-2′-deoxy-D-ribofuranosides (27–36) which can be regarded as 2′-deoxyadenosine analogs. Analogously reacted the 2-N,N-dimethyl-amino-methyleneimino-7(8H)pteridones (43–48) to give preferentially the corresponding N8-ß-D-anomers

  各种 4-氨基-7(8H) 蝶啶酮 (6, 12, 14, 15, 20, 22) 已被 1-氯-2'-脱氧-D-呋喃核糖衍生物 (25, 26) 糖基化，应用新的 DBU-盐法形成 N8-2'-脱氧-D-呋喃核糖苷 (27-36)，可视为 2'-脱氧腺苷类似物。2-N,N-二甲基-氨基-亚甲基亚氨基-7（8H）蝶啶酮（43-48）类似地反应，优先得到相应的 N8-β-D-端基异构体（49-55）。1-溴-2,3,5-三-O-苯甲酰基-aD-呋喃核糖 (56) 的核糖基化也与 6、12、15、45 和 46 一起进行，得到 N8-β-D-呋喃核糖苷 57– 61. 糖脱保护分别导致游离的 N8-2'-deoxy-ß-D-ribofuranosides 37-42 和 N8-ß-D-ribofurano-sides 62-65。在 Vorbrüggen 条件下通过甲硅烷基方法进行的糖基化与 6、12
