ABSTRACT Nitration of 9-substituted [ethyl, (Ac)2-2′-deoxyribosyl, (Ac)3-ribosyl] N 6-acetyladenine derivatives with Cu(NO3)2·3H2O/Ac2O was examined. Nitration proceeded at the 2-position, although the yield was low. Removal of the acetyl groups gave 2′-deoxy-2-nitroadenosine derivatives.

Abstract An efficient synthetic method has been developed for the synthesis of 2′-deoxyguanosine from the more commercially available 2′-deoxyadenosine via late-stage C2 nitration in 48.7% total yield by a 5-step synthetic procedure. Crucially, 2′-deoxyadenosine was fully protected by bennzoyl groups and then nitrated at C2 by tetrabutylammonium nitrate/trifluoroacetic anhydride. The resulting 2-NO2
