A series of hydurilic acid derivatives (5,5′-bipyrimidinyl-2,4,6,2′,4′,6′-hexaones) including several new derivatives was synthesized from 5,6-diaminouracils. Mechanisms for their formation are proposed and discussed. Furthermore, a new method for the preparation of pyrimidine-2,4,5,6-tetraone-5-oxime derivatives (violuric acids) was found starting from 5-amino-6-nitrosouracils.

The reaction of 5,6-diamino-1,3-dimethyluracil with 1,3-diaryl-2,3-dibromopropan-1-ones gave β-(5-amino-6-imino-1,3-dimethyluracil)chalcones, and conditions for their cyclocondensation to pyrimidinodiazepines were found.For substantiation of the reaction mechanism, the reaction of the diamine with other halogen derivatives of chalcones was studied.The IR, UV, and mass spectra of the synthesized compounds and their condensation products are discussed.
