Teh first step in the acid-catalyzed reaction of 5,6-diamino-1,3-dimethyluracil with carbonyl compounds is the formation of an azomethine at the 5-amino group.Chalcone derivatives undergo a further substitution; the 6-amino group is replaced by a hydroxyl group with subsequent ring closure and the formation of 2,3-dihydro-1,5-oxazepine ring.Azomethines based on arylidenacetones form 2,3-dihydropyrimidino-1,5-diazepine derivatives.

2,4-Diaryl-7,9-dimethyl-6,8-dioxo-2,3-dihydropyrimidino-1,5-oxazepines are formed instead of the expected dihydrodiazepine derivatives in the reaction of chalcones with 5,6-diamino-1,3-dimethyluracil (I) in the presence of acetic acid.The reaction
