  Synthesis of Different 3,5‐Diazidofuranoses: A New and General Synthesis Pathway

  摘要：

  Diamino- and diazidofuranoses represent useful precursors, for example, for the synthesis of substituted nucleosides and metal complexes, respectively. Known procedures for their synthesis lack the availability of cheap starting materials, adequate yields, and the access to all possible diastereomeres. Therefore, 3,5-diazido-3,5-dideoxy- and - 2,3,5- trideoxyfuranoses both with ribo- and xylo- configuration were prepared using different approaches.

  strategies were evaluated towards the preparation of (−)-(3R,4R)-1-benzyl-4-(benzylamino)piperidin-3-ol (1), which was constructed with control over the relative and absolute stereochemistry of the 4,3-amino alcohol moiety. The first strategy employed a novel RhI catalyzed asymmetric hydrogenation, while two other strategies exploited the existing stereochemistry in 2-deoxy-D-ribose, and the fourth explored

  1,2,3,4-Tetra-O-acetyl-5-thio-D-ribopyranose as well as its 1-bromide were used as donors in the reaction with 4-cyano- and 4-nitrobenzenethiol to give the corresponding thiogrycosides in different anomeric ratios depending on the reaction conditions. Zemplen deacetylation afforded 4-cyanophenyl as well as 4-nitrophenyl 1,5-dithio-alpha- and beta-D-ribopyranosides, respectively. 1,3,4-Tri-O-acetyl-2-deoxy-5-thio-D-erythro-pentopyranose was synthesized from methyl 2-deoxy-D-erythro-pentofuranoside and was coupled with 4-cyano- and 4-nitrobenzenethiol to give anomeric mixtures from which 4-cyanophenyl as well. as 4-nitrophenyl. 1,5-dithio-beta-D-erythro-pentopyranosides were isolated after deacetylation. 1,4-Di-O-acetyl-2,3-dideoxy-5-thio-D-glycero-pentopyranose was obtained starting from 1,2;5,6-di-O-isopropylidene-D-mannitol and used as the donor in the glycosylation reaction with 4-cyano- and 4-nitrobenzenethiol. The resulting anomeric mixtures were separated to give, after deacetylation, 4-cyanophenyl as well as 4-nitrophenyl 2,3-dideoxy-1,5-dithio-beta-D-glycero-pentopyranosides. All of these thioglycosides showed significant antithrombotic activity on rats after oral administration. (C) 1999 Elsevier Science Ltd. All rights reserved.
