Abstract:
Oxanine, one of major damaged product from deamination of guanine base mediated by NO or HNO2-induced nitrosative reaction, has been considered as a genotoxic lesion. To analyze the biophysical properties of oxanine in context of oligodeoxynucleotide, the chemical incorporation of 2'-deoxyoxanosine (dOxo, nucleoside form of oxanine) into oligodeoxynucleotide is required. Here, we developed the chemical synthesis procedures of dimethoxytritylated dOxo-phosphoramidite (DMT-dOxo-amidite) and oxanine-contained oligonucleotide.

Preparation of 1° Amines: Azide Synthesis
Azide ions act as good nucleophiles and react with unhindered alkyl halides to form alkyl azides. Alkyl azides do not participate in further nucleophilic substitution reactions, thereby eliminating the chances of polyalkylated products. Alkyl azides are reduced by hydride-based reducing agents, like lithium aluminum...
