Abstract
The syntheses of 7-halogenated derivatives 3b-e of 2-amino-7-deaza-2′-deoxyadenosine as well as 7-bromo and 7-chloro-7-deaza-2′-deoxyisoguanosines 4b-c are described. Nucleobase anion glycosylation was employed for the convergent nucleoside synthesis. The regioselective 7-halogenation was performed either on the nucleoside precursor 7 or on the nucleobase 12. Two bromo substituents were introduced in the 7- and 8-position when the unprotected 2-amino nucleoside 9 was used. Conformational analysis of the sugar moiety of nucleosides 3a-e and 4a-c was performed on the basis of vicinal 1H,1H NMR coupling constants.
