실험 절차

Matsumoto in Chem Pharm Bull, 36(3), 1153-1157 and JP 63-107982 teaches a process for the synthesis of acyclovir(Ia) by condensation of diacetyl guanine (DAG Va) with 2-oxa-1,4-butanediol diacetate (OBDDA, VIIa) in DMSO in presence of an acid catalyst to get a mixture of N-9/N-7 isomer (66:26). The former is isolated by column chromatography and deacetylated with methanolic ammonia to give acyclovir. Overall yield of acyclovir from guanine is 42%
