The synthesis of 4-(methylthio)-1H-imidazo[4,5-c]pyridine 2′-deoxy-β-D-ribonucleosides 2 and 9 and the conversion of the N1-isomer 2 into the 2′,3′-didehydro-2′,3′-dideoxyribonucleoside 3a or (via7) 3-deaza-2′-deoxyadenosine (1) is described. Phosphonate building blocks of 1 were employed in solid-phase synthesis of self-complementary base-modified oligonucleotides. Their properties were studied with
