  The cyclization of 6-(1,2-diethoxycarbonylethylidene)hydrazino-1,3-dimethyluracil (3) and 6-(1,2-diethoxycarbonylethylidene)hydrazino-3-methyl-2-methylthiopyrimidin-4(3H)-one (8) in the presence of polyphosphoric acid (PPA) provided 2,5-dihydropyrimido[4,5-c]-1,2-diazepine-5,6,8(1H,7H,9H)-trione (4) and 4,5-dihydropyrimido[4,5-c]-1,2-diazepine-5,6(1H,7H)-dione (9), respectively. 4-Hydrazino-5-methyl-2-pyrone (27) and 5,5-dimethyl-3-hydrazinnocyclohexen-1-one (31) readily reacted with ethyl benzoylacetate (28) to give 4,5-dihydropyrano[4,3-c]-1,2-diazepine-5 (30) and 3-phenyl-1,8,8-trimethyl-4,5,6,7,8,9-hexahydro-1,2-benzodiazepine-5,6(1H)-dione (33), respectively.

  The reaction of 6-hydrazinouracils (1) with 3-aryl-1,1,1-trifluoropropane-2,3-dione monohydrates (2) in refluxing ethanol in the presence of p-toluenesulfonic acid gave regioselectively 3-aryl-4-trifluoromethyl-5,6,7,8-tetrahydropyrimido[4,5-c]pyridazine-5,7-diones (4a-e) in moderate yields. The location of a trifluoromethyl group at the C4 position was elucidated on the basis of the chemical transformation of the derivatives.
