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.
