Amination of guanosine (Guo) with 2,4-dinitrophenoxyamine in aqueous DMF gave 7-amino-Guo, which was readily converted to 8,5'-O-cyclo-Guo, and 8-hydroxy-Guo. Deoxyguanosine (dG) gave only deglycosylated 7-amino-G under the same reaction condition. Aminations of Guo and dG with hydroxylamine-O-sulfonic acid above pH
