The synthesis of 8-aza-1,3-dideaza-2′-deoxyadenosine (3a) as well as of 4- and 5,6-substituted benzotriazole 2′-deoxy-β-D-ribonucleosides is described (Schemes 1–3). Glycosylation of benzotriazole anions is stereoselective in all cases (exclusive β-D-anomer formation), but regioisomeric N1, N2, and N3-(2′-deoxyribofuranosides) are formed. The distribution of the regioisomers is controlled by the nucleobase
