    摘要: The invention concerns compounds of the general formula (I) in which i:he residues R1 to R7 have the meanings given in the application as well as methods for their preparation. The compounds are in particular suitable as substrates for RNA or DNA polymerases and can thus be incorporated into RNA or DNA oligonucleotides and are especially suitable for labelling and detecting nucleic acids or for DNA sequencing.

    摘要: 2′-Deoxyisoguanosine, isosteric analogues and isoguanosine derivatives of formulae I-V, processes for their production via compounds of the general formulae a or b and reaction with aroyl isocyanates or from compounds of the general formulae VI-IX by photochemical irradiation. A further production process is the conversion of deoxyguanosines or guanosines by means of persilylation, reaction with ammonia and deamination in the 2 position. The compounds are suitable as pharmaceutical agents with antiviral efficacy.
