Kawashima, Etsuko published the artcileHighly diastereoselective synthesis of (2’S)-[2′-2H]-2′-deoxyribonucleosides from the corresponding ribonucleosides, Application of N-(9-((6aR,8R,9R,9aS)-9-Hydroxy-2,2,4,4-tetraisopropyltetrahydro-6H-furo[3,2-f][1,3,5,2,4]trioxadisilocin-8-yl)-6-oxo-6,9-dihydro-1H-purin-2-yl)isobutyramide, the publication is Nucleosides & Nucleotides (1995), 14(3-5), 333-6, database is CAplus.
The four (2’S)-[2′-2H]-2′-deoxynucleosides (>90 atom % 2H), were synthesized from the corresponding ribonucleosides involving six steps of reactions, i.e., oxidation of their 2′-hydroxyl group, stereoselective reductive deuteration of the resulting 2′-keto nucleoside intermediates with NaB2H4 in EtOH-H2O or EtOH, triflation, bromination with LiBr, highly stereoselective Bu3SnH-Et3B reduction of the resulting bromide, and, finally, unmasking.
