Abstract
Abstract Pentafluoropyridine reacts with thymidine, adenosine, and uridine hydroxy groups to give quantitative yields of the corresponding nucleoside di-and triaryl ethers. The nucleophilic substitution reactions proceed successively and in parallel, with the slowest step being the nucleophilic substitution of the nucleoside secondary hydroxyls. The resulting ethers contain tetrafluoropyridyl moieties, which could be smoothly modified by ...
