Several 5-amino and 5-glycosylaminopyrrolo[3,4-c]pyridin-1,3(2H)-dione derivatives and 7-amino and 7-glycosylaminopyrido[3,4-d]pyridazin-1,4(2H,3H)-dione derivatives, were synthesized starting from 2-amino and 2-glycosylaminopyridines, respectively. For the preparation of pyrrolopyridine and pyridopyridazine derivatives we used ammonia and hydrazine monohydrate respectively. Those compounds were evaluated

tandem Diels-Alder/Retro Diels-Alder (DA/RDA) reaction starting from 6-glycosylaminopyrimidines, 6, with dimethyl acetylenedicarboxylate (DMAD) as dienophile. This approach represents a newmethod for the synthesis of 2-aminopyridine nucleoside analogues. The compounds were tested for their antiviral activity but did not prove active.
