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.

Abstract In this work, an efficient and facile method for the preparation of 5-perfluoroalkylation uracils and uracil nucleosides through visible-light-mediated reaction has been developed. The reaction processes in high efficiency under mild reaction conditions and show broad substrate scope by employing commercial available perfluoroalkyl sources, thus demonstrates high potent application in life

perfluoroalkyl motifs in the core structure, access to such analogues typically requires multi-step synthesis. Here, we report a mild, metal-free and operationally simple strategy for the direct perfluoroalkylation of uracils, cytosines and pyridinones through a visible-light induced pathway from perfluoroalkyl iodides. This photochemical transformation features synthetic simplicity, mild reaction

Provided is a simple and efficient production process of a nucleobase having a perfluoroalkyl group.
A nucleobase (for example, uracils, cytosines, adenines, guanines, hypoxanthines, xanthines, or the like) is reacted with a perfluoroalkyl halide in the presence of a sulfoxide, a peroxide and an iron compound to produce a perfluoroalkyl-substituted nucleobase, which is useful as an intermediate for medical drugs, economically.
