New syntheses of pyrimidopyridazines from 6-hydrazinoisocytosines and vicinal carbonyl reagents and reduction studies with selected members of this compound series are reported.Structural features required for pyrimidopyridazine formation from reactions of 2-amino-4-hydrazinopyrimidines with vicinal difunctional reagents and selectivity with respect to product substituent orientations are summarized.
