A general synthesis of 2'-5' linked oligoribonucleotides has been achieved on the basis of chemoselective formation of the 2'-5' internucleotide linkage using N-unblocked nucleosides. The 2'-5' linked oligoadenylates (2-5As) produced from ATP in the

✦ Synopsis
The use of alkylsilyl protecting groups provides a rapid route to 3',5'diprotected ribonucleosides which are easily coupled via the phosphorodichloridite procedure to produce 2'-5' linked ribonucleotides.
It has recently been demonstrated l-3 that 2'-5' linked oligoadenylic

## Abstract 5′‐pACUG tetraribonucleotides containing 2′–5′ or 3′–5′ linkages self‐condensed on 2′–5′‐ or 3′–5′‐linked complementary decaribonucleotide (5′‐CAGUCAGUCA) templates. CD and UV melting studies showed that helix formation took place in all four possible combinations of linkage isomers of
Cleavage of 2'-0-tetrahydropyranyl groups from ribonucleoside derivatives used in solid-phase oligoribonucleotide synthesis takes place to an unacceptable extent during treatment with protic acid to remove 5'-O-pixyl groups.
