  Facile synthesis of 4-deoxy-4-fluoro-α-d-talopyranoside, 4-deoxy-4-fluoro-α-d-idopyranoside and 2,4-dideoxy-2,4-difluoro-α-d-talopyranoside

  摘要：

  The title compounds were prepared by two independent syntheses using inexpensive commercially available starting materials. 4-Deoxy-4-fluoro-alpha--talopyranoside served as a precursor to 4-deoxy-4-fluoro-alpha-D-idopyranoside, allowing for inversion of configuration at C-3 via a three-step protocol. The synthesis of 2,4-dideoxy-2,4-difluoro-alpha-D-talopyranoside is based on two nucleophilic fluorination events at C-2 then at C-4 using TBAF center dot 3H(2)O and TBAF.4tBuOH as a fluoride source. All compounds are prepared as pure stereoisomers and are therefore suitable probes for OH center dot center dot center dot F H-bonding studies by (1)H NMR spectroscopy. (C) 2011 Elsevier B.V.
