The synthesis of fluorescent N6-methyl-2-(1,2,3-triazol-1-yl)-2′-deoxyriboadenosine (AOz) was achieved by methylamine induced nucleophilic aromatic substitution of the corresponding 2,6-bis-(1,2,3-triazol-1-yl)purine 2′-deoxyribonucleoside. The developed fluorophore exhibits quantum yields of 20% and 12% in methanol and water, respectively. It was further applied in the synthesis of trinucleotide GAOzC which sustains a reasonable Stokes shift of 121 nm and 7% quantum yield upon irradiation at 310 nm. It was also demonstrated that Cu(I) species reduce 2,6-diazido purine derivatives regioselectively at C(6) providing a practical entry to 6-amino-2-azido-purine nucleosides.
