Regioselective alkylation of guanines using 2-acetoxytetrahydrofurans
摘要:
Reaction of silylated guanine derivatives with 2-acetoxy-4-benzoyloxymethyltetrahydrofuran in DMF or NMP resulted in selective N-9 alkylation. This was used as the basis for a regioselective synthesis of the anti-viral agents famciclovir and penciclovir. (C) 2001 Elsevier Science Ltd. All rights reserved.
