Abstract
The four (2'S)-[2'-H-2]-2'-deoxynucleosides (>90 atom % H-2),,ere synt hesized from the corresponding ribonucleosides involving six steps of reactions, i.e., oxidation of their 2'-hydroxyl group, stereoselective reductive deuteration of the resulting 2'-ketonucleoside intermediate s with (NaBH4)-H-2 in EtOH-H2O or EtOH, triflation, bromination with L iBr, highly stereoselective Bu(3)SnH-Et(3)B reduction of the resulting bromide, and, finally, unmasking.
