Abstract
A convenient synthesis of 2'-deoxy-2-fluoro-adenosine (1) is described. Dea minative 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 derivati ve 5a followed by treatment with an excess of tris(trimethylsilyl)silane (T TMSS) and tert-butyl peroxide in toluene at 80 degrees C was found to affec t an efficient deoxygenation to the corresponding 2'-deoxy derivative 6. De silylation of 6 by Et4NF in CH3CN afforded 1 in high yield.
