Novel purine nucleosides with a N-tert-butylhydroxylamino group at the 2-position of purine nucleus (1-3) were synthesized, which might prefer anti conformation and would not perturb DNA structure when incorporated into oligonucleotide. Oxidation of 1-3 by treatment with Ag2O or air afforded stable aminoxyl radicals (1'-3') and their properties were studied by EPR spectroscopy. 5-N-tert-butylhydroxylamino uridine (4) was also synthesized.
