2- O -Ethyluracils were silylated with HMDS and condensed in the presence of TMS -triflate with β-D-glucose pentaacetate to give the corresponding β-nucleosides. Alternatively, these could be synthesized by nucleoside coupling of 2,3,4,6-tetra- O -acetyl-α-D-glucopyranosyl bromide with the sodium salts of 2- O -ethyluracils, which were deprotected with saturated ammonia in methanol. 6′- O -Tosylate
