3′,5′-O-Tetraisopropyldisiloxanylnucleosides smoothly react with 2-methoxypropene to give 2′-O-(1-methyl-1-methoxy)ethyl nucleosides in high yields without formation of diastereoisomers. These nucleosides were used as intermediates for oligonucleotidesynthesis by the phosphotriester method. The (1-methyl-1-methoxy)ethyl group was removed rapidly from oligonucleotides by acid treatment.
