  Synthesis of 6-fluoro-d-olivose (2,6-dideoxy-6-fluoro-d-arabino-hexopyranose)

  摘要：

  An efficient synthesis of 6-fluoro-D-olivose 5 (2,6-dideoxy-6-fluoro-D-arabino-hexopyranose starting from D-glucose is reported. Key features of the synthesis involve the early introduction of the fluorine atom at C-6 and the Fischer reductive elimination as a strategy to achieve C-2 deoxygenation. The route, the first to this compound, is efficient providing gramme quantities of 5 for biotransformation studies. (C) 1998 Elsevier Science S.A. All rights reserved.

  Application of the Synthetic Aminosugars for Glycodiversification:  Synthesis and Antimicrobial Studies of Pyranmycin

  摘要：

  A divergent approach was employed for the synthesis of aminosugars, from which a novel library of aminoglycoside antibiotics (pyranmycins) was synthesized. Pyranmycins have comparable antibacterial activity as neomycin, a clinically used aminoglycoside antibiotic, against Escherichia coli, Staphylococcus aureus, Bacillus subtilis, and Mycobacterium smegmatis. In addition, pyranmycins, like streptomycin, are bacteriocidal while isoniazid (INH) is bacteriostatic. Therefore, pyranmycins may provide new therapeutic options in the treatment against tuberculosis. Several members of pyranmycins also manifest modest anti-Tat and anti-Rev activities, which may aid in the development of new anti-HIV agents. Although the antibacterial activity of pyranmycins against aminoglycoside resistant bacteria is less than expected, the synthetic methodologies of utilizing a library of aminosugars can be a model for future studies of glycodiversification or glycorandomization.

In contrast, the kinetic analysis of GDP-ManPP was only possible with three out of eight analogues. The pKa2 values of analogues (1–3) were determined by proton decoupled 31P and 19F NMR titration experiments. Counterintuitively, the axial fluoro substituent in 3 did not change chemical shift upon

  For studies on the recognition mechanisms for Glycyrrhizin-induced biological activities, seven Glycyrrhizin analogues with 3'-,4'-,6'-,3-, and 4-fluorinated 2-O-beta-D-glucopyranosyl-beta-D-glucopyranoses (1-5) and 3- and 4-fluorinated 2-O-beta-D-glucopyranuronosyl-beta-D-glucopyranoses (6 and 7) were synthesized through a stepwise glycosylation procedure. 1,2-Di-O-acetyl-4,6-di-0-benzyl-3-deoxy-3-fluoro- (13) and 1,2-di-O-acetyl-3,6-di-O-benzyl-4-deoxy-4-fluoro-D-glucopyranose (14) were employed for the first beta-glycosylation of methyl glycyrrhetate, promoted with trimethylsilyl trifluoromethanesulfonate.
