Configurational stability of dinucleoside H-phosphonates and the stereochemical course of their sulfurisation in the presence of diazabicyclo[5.4.0]undec-7-ene (DBU) were investigated using 31 P NMR spectroscopy. It was found that under the rea

Dideoxyribonucleoside phosphorothioates were synthesized by a new method via dideoxyribonucleoside 2,2,2-trichloroethoxycarbonylphosphonates and aroylphosphonates.The conversion of dideoxyribonucleoside 2,2,2-trichloroethoxycarbonylphosphonates to dideoxy

Dideoxynucleoside phosphorothioates were synthesized by a new mwthod via dideoxynucleoside aroylphosphonates.The aroyl groups were easily removed from 1 and 2 by the action of n-BuNH2 and in situ converted to only one diastereomer (Rp configura

Dithymidine phosphonate (10) was synthesized by a new method via dithymidine aroylphosphonates (3) in which the aroyl group served as a protecting group for O=P-H functions.In a way analogous to the phosphotriester method, 3 was prepared by successive con
