,3]dioxolan-2-yl as a newprotecting for the 2′-hydroxyl function. Our cyclic orthoester-type group is compatible with the DMTr strategy for oligonucleotide synthesis. This group was introduced to the 2′-hydroxylgroup of appropriately protected nucleoside derivatives in good yields under mild acidic conditions. Post-synthetic conversion of the moiety of this protectinggroup with an amine resulted

3-dioxolan-2-yl (DECDO) in view of its use as a protectinggroup for the 2′-hydroxyl function of ribonucleosides. The DECDO group is found to be compatible with the DMTr strategy for the currently-used oligonucleotide synthesis. Post-synthetic treatment with ammonia results in the conversion of this protectinggroup into the 4,5-dicarbamoyl-1,3-dioxolan-2-yl (DCBDO) group which is unexpectedly more stable in
