摘要:
A variety of modified nucleosides or dinucleosides bearing one of the following functions have been prepared: N-hydroxyureas, N-hydroxyamines, N-hydroxycarbamates, alpha-(N-hydroxyamino)phosphonates. Upon oxidation, these compounds afford the corresponding aminoxyl free radicals which have been studied by EPR spectroscopy. Some of these compounds exhibited antiviral properties.
