Nucleosideanalogs that project substituents into the minor groove when incorporated into duplex RNA perturb the binding of proteins and can affect basepairing specificity. The synthesis of 2-aminopurine ribonucleoside analogs and their phosphoramidites, their incorporation into duplex RNA, their postsynthetic modification via Cu-catalyzed azide−alkyne cycloaddition (CuAAC), and their effect on duplex
