Abstract
The ozonation of 4-thiopyrimidine and 6-thiopurine nucleosides in presence of amines afforded selectively and under mild experimental conditions several cytidine and adenosine nucleosides. The same reaction carried out in presence of alcohols afforded O4-or O6- alkylated derivatives of the nucleosides.
