Transformation of DinucleosideS-Aryl Phosphorothioates into the CorrespondingO-Alkyl Phosphates by Use of Tributyltin Alkoxides

Several alkyl dinucleoside phosphotriesters were easily obtained by use of the reaction of S-aryl dinucleoside phosphorothioates with tributyltin alkoxides. This reaction proceeds at room temperature under neutral conditions.
