The potent and selective antiviral drug ganciclovir (6) has been synthesized in two steps via transpurination of fully acetylated guanosine (1) in the presence of 1,3-diacetoxy-2-(acetoxymethoxy)propane (2), followed by deacetylation in aqueous ammonia. The transpurination reaction also provides valuable side products, tetra-O-acetyl-β-D-ribofuranose (5) and the 7-regioisomer of triacetylganciclovir (4); the latter product can be converted to the desired 9-isomer in a thermal 7 ? 9 isomerization.
