A simple and efficient method for the preparation of pyrimidine 2'-O-hydroxyethoxymethylribonucleosides and 2'-O-hydroxypropoxymethylribonucleosides has been developed. These modified nucleosides were incorporated into oligoribonucleotides, which were shown to form stable RNA/RNA duplexes. The effect of 2'-O-modification in the antisense and sense strands of small interference RNA was evaluated in multi-drug resistant NIH 3T3 cells.
