Abstract:
Highly stereoselective synthesis of (2'R)-[2'-2H]-2'-deoxyribonucleosides (2'R:2'S = > 99:1) were accomplished by treating 2'-bromo-3',5'-O-TPDS-2'-deoxyribonucleosides with tributyltin deuteride at lower temperatures such as -60 degrees C in the presence of triethylborane. Moreover, synthesis of some oligodeoxyribonucleosides involving them will be described.
