  Nucleosides. LIV¹Synthesis and Properties of 3′-Azido- and 2′,3′-Dideoxy-6,7-diphenyllumazine Nucleosides

  摘要：

  The best approach for the synthesis of 1-(3-azido-2,3-dideoxy-beta-D-erythro-pentofuranosyl)lumazine (5) and its 6,7-dimethyl- (4) and 6,7-diphenyl derivatives (3) has been found in the interconversion of the corresponding 1-(2-deoxy-beta-D-threo-pentofuranosyl)-lumazines. Monomethoxytritylation at the 5'-position (1 7, 3 4, 4 9) followed by mesylation at the 3'-OH group and subsequent nucleophilic displacement by lithium azide afforded 1 9, 2 9 and 4 7 which were deprotected by acid treatment to give 3-5 in good yields. The syntheses of 1-(2,3-dideoxy-beta-D- glycero-pentofuranosyl)-6,7-diphenyllumazine (6) and its 6,7-dimethyl derivative (7) were achieved from 1-(2-deoxy-beta-D-erythro-pentofuranosyl)- 6,7-diphenyllumazine and the corresponding 6,7-dimethyllumazine (2 6) via their 5'-O-p-toluoyl- (2 0, 3 0), and 3'-deoxy-3'-iodo derivatives (2 4, 3 1) to form, after radical dehalogenation and final deprotection, 6 and 7. The newly synthesized lumazine nucleosides have been characterized by elemental analyses, UV- and NMR spectra.

  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.

  conditions led to selective 2,2′-cyclization but no products possessing the less favored 4,2′-structure were obtained. The best yields of 2,2′-anhydro-3-β- d -arabinofuranosyllumazines were obtained from 3-(2,3- O -carbonyl-5- O -trityl-β- d -ribofuranosyl)lumazines in an imidazole-catalyzed reaction at elevated temperatures. Base hydrolysis of the 2,2′-bond allowed the synthesis of 3-β- d -arabinofuranosyllumazines

  摘要研究了3-β-d-核呋喃呋喃糖基鲁嗪及其6,7-二甲基和二苯基衍生物与糖苷配基的相邻羰基形成脱水核苷的反应。各种条件导致选择性的2,2'-环化，但未获得具有较不受欢迎的4,2'-结构的产物。在咪唑催化下，由3-（2,3- O-羰基-5-O-三苯甲基-β-d-呋喃呋喃糖基）lumazines获得2,2'-脱水-3-β-d-阿拉伯呋喃糖基lumazines的最佳收率在高温下反应。2，2′-键的碱水解允许合成3-β-d-阿拉伯呋喃糖基lumazines。
