摘要:
2-Azidoadenosine (1) was synthesized in an overall yield of 49% from guanosine via the reaction of 9-(2',3',5'-tri-O-acetyl-beta-D-ribofuranosyl)-2-amino-6-chloropurine (2) with isoamyl nitrite and trimethylsilyl azide under neutral and anhydrous conditions. As photoaffinity probes, ATP analogues and the cap structure of eukaryotic mRNA bearing 2-azidoadenosine were synthesized.
