Abstract
Oligodeoxynucleotides (ODNs) containing 2-N-tert-butylaminoxyl-2'-deoxyadenosine (A*) residues were synthesized to allow accurate monitoring of adenine motion by EPR spectroscopy through the agency of direct linkage of the acyclic aminoxyl group to the nucleobase, and EPR studies of the ODNs in single- and double-stranded forms were performed. Upon duplex formation, peak broadening and decreases in peak height were observed in EPR spectra, and the synthesized ODNs were shown to be excellent monitors of hybridization. Comparison of peak height and the h1 /h0 signal ratio provided information on the relative mobility of A* in duplexes with different stability. A second set of ODNs each containing two A* residues at different intervals and four dA residues were also synthesized. For these ODNs, correlations were observed between the EPR spectral shapes of the duplexes and the number of dA residues between A* residues, thus demonstrating the potential of A* residues in monitoring of the structures of nucleic acids.

Abstract
A stable guanine-substituted nitronyl nitroxide radical 1 has been synthesized and characterized. The single-crystal structure analyses and magnetic susceptibility measurements exhibit a one-dimensional architecture of guanine base resulting from carbonyl-amino hydrogen bonds in the solid state, giving a 1D ferromagnetic chain of the radical moieties.

Abstract
[Structure: see text] 2'-Deoxyribofuranosylpurine derivatives bearing an N-tert-butylaminoxyl group (1a and 2a) were synthesized via oxidation of the corresponding N-tert-butylhydroxylamines (1b and 2b), which were synthesized by lithiation of 8-TIPS-6-chloropurine (3) at the 2-position and the following reaction with 2-methyl-2-nitrosopropane. Treatment of 1b and 2b with 1 equiv of NaIO4 resulted in efficient formation of 1a and 2a, which were isolated as purple and red solids, respectively. The EPR spectra of 1a showed pH dependency due to structural change of purine moiety.
