Abstract

(Chemical Equation Presented) Phosphate monoesters are synthesized from a mixture of phosphoric acid (1 or 2 equiv) and alcohols (1 equiv) in the presence of tributylamine. The reaction is promoted by nucleophilic bases such as N-alkylimidazole and 4-(N,N-dialkylamino)pyridine. 2′,3′-I- Isopropylidene ribonucleosides are selectively converted to their 5′-monophosphates without the protection of amino groups in nucleobases.
