High-yield regioselective synthesis of 9-[(2-hydroxyethoxy) methyl]guanine (Acyclovir 1, Scheme 1) was achieved from guanine via trisilylated guanine. N 2-acylacyclovir 9a–9b were prepared from N 2, O-diacylacyclovir (4, 8b–8d) using regioselective deacylation procedure. N 2- Acylacyclovir 11 and 13 were prepared via protection of primary hydroxyl groups. Three amino acidesters of acyclovir were synthesized
