Introduction of α-fluorophosphonomethyl ether functionality and its application to the synthesis of fluorinated acyclic phosphonate nucleosides
摘要:
Introduction of the alpha-fluorophosphonomethyl ether functionality has been achieved by electrophilic fluorination of the corresponding phosphonomethyl ether carbanion. Coupling of the synthesized 2-[(diethoxyphosphono)fluoromethoxy]ethanol (9) with adenine and 6-chloropurine under Mitsunobu conditions afforded novel fluorinated acyclic phosphonate nucleosides 11a and 11b, respectively.

A number of methyl derivatives of 9-[2-(phosphonomethoxy)ethyl]guanine (PMEG, 1) have been synthesized and tested in vitro for anti-herpes and anti-human immunodeficiency virus (HIV) activity. Among these analogues, (R)-2'-methyl-PMEG [(R)-3] and 2',2'-dimethyl-PMEG (7) demonstrated potent anti-HIV activity in the XTT assay with EC50 values of 1.0 and 2.6 microM, respectively. The corresponding (S)-2'-methyl-PMEG
