## Abstract The synthesis of 6โ€substituted 1โ€deazapurine 2โ€ฒโ€deoxyribonucleosides is described. Glycosylation of the 1โ€deazapurine (imidazo[4,5โ€__b__]pyridine) anions with the ฮฑโ€Dโ€halogenose 5 gives stereoselectively __N__^7^โ€ and __N__^9^โ€ regioisomers. ^1^Hโ€NMR NOE and ^13^Cโ€NMR spectroscopy are u
