Oligonucleotides containing pyrazolo[3,4-d]pyrimidines: 8-aza-7-deazaadenines with bulky substituents in the 2- or 7-position

□ The synthesis of the 2′-deoxyadenosine analogues 1b, 2b, and 3c modified at the 7- and/or 2-position is described. The effect of 7-chloro and 2-methylthio groups on the duplex stability is evaluated. For that, the nucleosides 1b, 2b, and 3c were convert
