of choice for selective deacylation of N- or/and O-acyl protected nucleosides without notable cleavage of 3′,5′-TIPDS group. Several examples of the developed protocol for the preparation 2′-O-modified nucleosides with overall high yields are presented. nucleosides - blocking group stability - tetraisopropyldisiloxane-1,3-diyl - protectinggroup - N-deacylation - O-deacylation
