One-step to get 5-azidomethyl-2′-deoxyuridine from 5-hydroxymethyl-2′-deoxyuridine and detection of it through click reaction

Nowadays a few ways to synthesize 5-azidomethyl-2′-deoxyuridine from 5-hydroxymethyl-2′-deoxyuridine have been reported. But none of them was one-step. And many of them need to protect the hydroxyl group on the pentose ring. The detection of 5-hydroxymethyl-2′-deoxyuridine is also very important in many biological processes. However few fluorescence detection strategies have been tried to do this. Herein, we reported a one-step protocol to synthesize 5-azidomethyl-2′-deoxyuridine, which was then used for detecting 5-hydroxymethyl-2′-deoxyuridine through a click reaction.
