Abstract: The phosphorothioate analogues of adenylyl(2'5')adenosine, adenylyl(3'5)-adenosine, adenylyl(5'5')adenosine and adenylyl(2'5')-P-thioadenylyl(3'5')adenosine and adenylyl(2'5')-P-thioadenylyl(2'5')adenosine have been synthesized using salicylchlorophosphite for formation of internucleoside phosphodiester bonds. In the case of (2'5') and (3'5') dimers, all compounds were] obtained as individual Rp-and Sp-diastereosomers. The structure of the synthesized compounds was confirmed by UV, CD and 1H NMR spectroscopy data, and enzymatic hydrolysis.
