  Synthesis and biological evaluations of certain 2-halo-2'-substituted derivatives of 9-.beta.-D-arabinofuranosyladenine

  摘要：

  The synthesis of a series of 2-chloro- or 2-fluoro-9-(2-substituted-2-deoxy-beta-D-arabinofuranosyl)adenines (4g-n) is described. New compounds were prepared from either 2-chloroadenosine or 2-fluoroadenosine by first blocking the 3'- and 5'-hydroxyls as the tetraisopropyldisiloxane derivatives. Activation of O-2' by formation of a triflate followed by nucleophilic displacement allowed introduction of various groups in the proper configuration at C-2'. Fluoride ion treatment then produced the deblocked nucleosides. All of the new compounds were evaluated as cytotoxic agents against L1210 and H.Ep.-2 cells and as antiviral agents against herpes simplex viruses 1 and 2 and vaccinia virus in culture.

  A convenient synthesis of 2'-deoxy-2-fluoro-adenosine (1) is described. Deaminative fluorination of 2-aminoadenosine (2) followed by silylation of the 3', 5'-hydroxyl groups gave the corresponding 2-fluoroadenosine derivative 4 in good yield. Thiocarbonylation of 4 to thiocarbonylimidazolyl derivative 5a followed by treatment with an excess of tris(trimethylsilyl)silane (TTMSS) and tert-butyl peroxide in toluene at 80 degrees C was found to affect an efficient deoxygenation to the corresponding 2'-deoxy derivative 6. Desilylation of 6 by Et4NF in CH3CN afforded 1 in high yield.
