Treatment of 2,2'-anhydro-1-(3'-O-tosyl-β-D-arabinofuranosyl) uracil (I) with sodium bromide, sodium ethanethiol, or sodium azide afforded 2,2'-anhydro-1-(3'-substituted-β-D-arabinofuranosyl) uracil (II), (III), or (IV). This result shows that 3'-tosyloxy group of I is displaced by above various nucleophiles without net inversion.
