A useful route to obtain trisubstituted pyrazolo[3,4-d]pyrimidines 14–17 is described. Those later were coupled with the alkylating agents 18–20 as in ACV, HBG, and iso-DHPG to give, after deprotection, the desired acylonucleosides 33–44. Almost all of the new compounds were evaluated for their inhibitory effects against the replication of various DNA viruses in culture.
