2'-Deoxynucleosides through 2'-thio-S-acetyl participation

Srihari Pabbaraja and Spencer Knapp. Rutgers University, Piscataway, NJ

The synthesis of 2'-deoxynucleosides has been simplified through the use of the 2'-thio-S-acetyl participating group to direct N-glycosylation. Donor (1) reacts under Vorbruggen conditions to give a nucleoside that is desulfurized with Ra-Ni to give, for example, 2'-deoxyribavirin (2).
