Methods for the regioselective alkylation at the 2′-hydroxy position over the 3′-hydroxy position of nucleosides and nucleoside analogs, forming 2′-O-ester modified compounds, are disclosed. Reduction and derivatization of the 2′-O-ester provides 2′-O-modified nucleosides and nucleoside analogs useful for the synthesis of oligomeric compounds having improved hybridization affinity and nuclease resistance.
