Disaccharide nucleosides: Synthesis of pyrimidine 5′-O-β-D-ribofuranosylribo- and -2′-deoxyribonucleosides

Rodionov,Efimtseva,Fomicheva,Padyukova,Mikhailov

, p. 179 - 185 (2007/10/03)

The easy synthesis of pyrimidine 5′-O-β-D-ribofuranosyl nucleosides from 2′,3′-di-O-acetylribonucleosides and 3′-O-tert-butyldiphenylsilyl-2′-deoxyribonucleosides is described. The stability upon O-glycosylation of various protecting groups is studied. Th
