Facile perfluoroalkylation of uracils and uridines at the C-5 position
摘要:
Perfluoroalkylation at the C-5 position of uracil has been achieved in yields of 38-56% by the reaction of its bis(trimethylsilyl) derivative with bis(perfluoroalkanoyl) peroxides and the hydrolytic deprotection of the silylated products. A substituent or nitrogen replacement at C-6 does not interfere with perfluoroalkylation at C-5, but no significant reaction occurs at C-6 when C-5 is blocked.
