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.

2'-Deoxyisoguanosine, isosteric аналоги и производные isoguanosine формул IV, процессы для их продукции через смеси вообще формул а или б и реакция с изоцианатами aroyl или от смесей вообще формул VI-IX фотохимическим облучением. Более дополнительным производственным процессом будет преобразованием deoxyguanosines или guanosines посредством persilylation, реакцией с амиаком и дезаминированием в положении 2. Смеси целесообразны как фармацевтические вещества с противовирусным efficacy.
