2-Alkoxy-2-thiono-1,3,2-oxathiaphospholanes are readily transformed into phosphorothioate monoesters of the corresponding alcohols in a one-pot process, involving the reaction with 3-hydroxypropionitrile in the presence of DBU, followed by treatment with aqueous ammonia. In this way a series of nucleoside-3′-O- and 5′-O-phosphorothioates were prepared, as well as phosphorothioate derivatives of selected polyols.
